Product details
Overview
HMC615LP4ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC mixer with integrated LO amplifier, designed for RF-to-IF downconversion in 2.3–4.0 GHz systems. It delivers +35 dBm input IP3, 10 dB typical conversion loss, and operates from a single +5 V supply at 65 mA - enabling high-linearity signal processing in wireless infrastructure transceivers.
For engineers reviewing the HMC615LP4ETR datasheet, HMC615LP4ETR pinout, HMC615LP4ETR application, or HMC615LP4ETR equivalent, this page provides verified electrical specs, validated pin functions, real-world use cases in PCS/3G and WiMAX base stations, and two confirmed alternative mixers with documented performance trade-offs.
Technical Context
The HMC615LP4ETR integrates a high-gain LO amplifier and passive double-balanced mixer core on a single GaAs die, eliminating external baluns and supporting DC–1 GHz IF output. Its RF and LO ports are DC-coupled and internally matched to 50 Ω, requiring only external DC blocking capacitors.
LO drive sensitivity ranges from –2 to +6 dBm, and the IC achieves 15 dB LO-to-RF isolation and 10 dB SSB noise figure at 200 MHz IF. The design positions LO amplifier output adjacent to mixer input to allow insertion of an external LO filter - a key feature for spurious suppression in dense spectral environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 2.3–4.0 GHz - defines usable band for cellular and fixed wireless front-ends without tuning. |
| IF Frequency Range | DC–1.0 GHz - supports zero-IF and low-IF architectures including direct-conversion receivers. |
| Input IP3 | +35 dBm - enables handling of strong interferers in multi-carrier base station environments. |
| Conversion Loss | 10 dB (typ.) - sets minimum gain budget required in receive chain before ADC. |
| LO Drive Level | –2 to +6 dBm - reduces need for external LO buffer stages in compact RF modules. |
| Supply Current | 65 mA @ +5 V - determines thermal load and power rail sizing for PCB layout. |
| Noise Figure | 10 dB (SSB) - impacts system sensitivity in wideband receiver designs. |
Pinout & Package
24-lead 4×4 mm QFN package with exposed ground paddle; RoHS-compliant matte tin finish, MSL1 rating, and 260 °C peak reflow profile. All ground leads and paddle must be soldered to PCB RF ground per Hittite land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MIX LO | DC-coupled LO input to mixer core; requires external DC blocking capacitor. |
| 3 | BIAS | LO amplifier bias supply node; requires external 18 Ω resistor and three bypass capacitors. |
| 4 | GND | Ground reference for internal circuitry; connects to exposed paddle for thermal and RF grounding. |
| 5 | LO | DC-coupled LO amplifier input; matched to 50 Ω, requires external DC blocking capacitor. |
| 10 | IF | DC-coupled IF output; supports DC–1 GHz operation but must not source/sink >18 mA. |
| 18 | RF | DC-coupled RF input; 50 Ω matched, requires external DC blocking capacitor. |
| 2,6–9,11–17,19–24 | N/C | No-connect pins; may be tied to RF ground without performance impact. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LO amplifier | Eliminates discrete LO buffer stage, reducing component count and board area in compact transceivers. |
| +35 dBm input IP3 | Enables robust operation in high-dynamic-range environments like multi-carrier BTS with adjacent channel interference. |
| No external baluns required | Simplifies layout and improves repeatability by removing sensitive transformer-based matching networks. |
| DC–1 GHz IF bandwidth | Supports flexible IF architecture selection including zero-IF, complex IF, and wideband digitization. |

Applications
| PCS / 3G Base Stations | WiMAX / WiBro Infrastructure |
|---|---|
|
Use Scenario: Downconverting 2.5–2.7 GHz PCS signals in macrocell BTS receive paths with multi-carrier loading. IC Role / Device Role / Timing Role: High-linearity active mixer providing RF-to-IF translation with integrated LO amplification. Use Value: +35 dBm IP3 maintains signal integrity under strong blocker conditions; 10 dB conversion loss aligns with LNA+filter+ADC chain gain planning. |
Use Scenario: IF sampling in 3.3–3.8 GHz WiMAX base station remote radio heads with DC–1 GHz IF interface to FPGA-based digital front-end. IC Role / Device Role / Timing Role: DC-coupled mixer delivering wide IF bandwidth for complex I/Q demodulation. Use Value: DC–1 GHz IF range enables direct connection to high-speed ADCs without IF filtering or frequency translation stages. |
| ISM Band Fixed Wireless | Repeaters & Small Cells |
|
Use Scenario: 2.4 GHz ISM-band point-to-multipoint access points operating in noisy industrial RF environments. IC Role / Device Role / Timing Role: Front-end mixer rejecting out-of-band interferers via high LO-to-RF isolation (15 dB typ). Use Value: 15 dB LO-to-RF isolation minimizes LO leakage into antenna path, easing filter requirements and improving EIRP compliance. |
Use Scenario: Indoor femtocell and outdoor small cell units requiring compact, low-power RF front-ends for 2.3–2.7 GHz LTE bands. IC Role / Device Role / Timing Role: Low-LO-drive mixer reducing power consumption and heat generation in thermally constrained enclosures. Use Value: –2 to +6 dBm LO drive range allows direct connection to low-power synthesizers, avoiding extra buffer stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-IP3 mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC551LP4E | Wider RF/LO range (0.8–4.0 GHz), same 4×4 mm QFN package and pinout. | Better suited for multi-band radios covering GSM/UMTS/LTE low bands; slightly lower IP3 (+33 dBm typ). | Select when broader frequency coverage is needed and +2 dB IP3 margin can be traded for band flexibility. |
| HMC215LP4E | Same pinout and package; lower IP3 (+29 dBm), higher conversion loss (12 dB), wider 0.8–4.0 GHz range. | Targeted at cost-sensitive, lower-performance repeaters where linearity requirements are relaxed. | Choose for legacy or budget-tier designs where +6 dB IP3 headroom is not required and LO drive tolerance is less critical. |
Compared with HMC551LP4E and HMC215LP4E, the HMC615LP4ETR offers the highest input linearity (+35 dBm IP3) within its 2.3–4.0 GHz band, making it optimal for high-density spectrum deployments where intermodulation distortion must be minimized - without requiring PCB redesign due to pin compatibility across all three variants.

FAQ
What is the operating temperature range for the HMC615LP4ETR?
The HMC615LP4ETR is specified for continuous operation from –40 °C to +85 °C ambient temperature. Junction temperature must not exceed 150 °C, and thermal resistance from junction to ground paddle is 192 °C/W - requiring proper PCB copper pour and via stitching to maintain reliability under full-load conditions. The HMC615LP4ETR datasheet confirms these limits in the Absolute Maximum Ratings table.
Does the HMC615LP4ETR require external baluns?
No, the HMC615LP4ETR does not require external baluns. Its internal mixer core and port matching are designed for direct 50 Ω interfacing on RF, LO, and IF ports. The HMC615LP4ETR functional diagram and application circuit confirm fully unbalanced, DC-coupled I/O with no balun components shown or required in the recommended layout.
What is the recommended LO drive level for optimal performance of the HMC615LP4ETR?
The HMC615LP4ETR achieves best linearity and conversion loss across its band with LO drive between –2 dBm and +6 dBm. At +4 dBm LO, typical conversion loss is 10 dB and input IP3 reaches +35 dBm. Driving below –2 dBm increases conversion loss; above +6 dBm risks exceeding absolute maximum LO input rating of +10 dBm and may degrade reliability. This range is specified in the HMC615LP4ETR Electrical Specifications table.
Can the HMC615LP4ETR be used in upconverter configurations?
Yes, the HMC615LP4ETR supports upconversion. Application note figures show upconverter performance at IF = 100 MHz, confirming functional bidirectional operation. However, its primary characterization and optimization are for downconversion; upconverter conversion gain and spurious performance must be verified per application circuit and layout. The HMC615LP4ETR evaluation board (PCB #113417) supports both modes.
Is the HMC615LP4ETR pin-compatible with other Hittite mixer variants?
Yes, the HMC615LP4ETR is pin-for-pin compatible with HMC551LP4E and HMC215LP4E, sharing identical 24-lead 4×4 mm QFN footprint, pad layout, and terminal functions. This allows drop-in replacement in existing designs targeting different frequency bands or linearity requirements - confirmed in the HMC615LP4ETR General Description section and Pin Descriptions table.
