Product details
Overview
HMC622LP4 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC mixer IC with integrated IF and LO amplifiers, designed for RF upconversion and downconversion in 1.8–3.9 GHz systems. It delivers +23 dBm input IP3, 9 dB typical conversion gain (downconverter mode), and operates with only +3 dBm LO drive. Its primary role is as a high-linearity signal translation stage in wireless infrastructure transceivers.
For engineers reviewing the HMC622LP4 datasheet, HMC622LP4 pinout, HMC622LP4 application, or HMC622LP4 equivalent, this device is selected for compact, high-dynamic-range RF front-ends requiring low LO power, wide RF bandwidth, and integrated amplification - especially where SSB noise figure ≤10 dB and LO-to-RF isolation ≥33 dB are critical.
Technical Context
The HMC622LP4 integrates a double-balanced mixer core with monolithic IF and LO amplifiers on a single GaAs die, enabling full-conversion functionality without external gain stages. Its architecture supports both upconversion (12 dB gain) and downconversion (9 dB gain) modes using the same RF/LO/IF port assignments and bias configuration.
It features DC-coupled RF, LO, and MIXLO ports matched to 50 Ω, AC-coupled IFOUT, and an IFIN port with internal 51 nH inductor to ground. Biasing requires separate VddIF (+5 V) and BIAS (+5 V) supplies, drawing 175–220 mA total under typical operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.8–3.9 GHz - Enables direct use across PCS, WCDMA, TD-SCDMA, WiMAX, and WiBro bands without external filtering or tuning. |
| IF Frequency Range | 200–550 MHz - Supports standard IF architectures including 468 MHz SSB receivers and 250 MHz baseband interfaces. |
| Input IP3 (Downconv.) | +23 dBm - Allows handling of strong adjacent-channel interferers in dense cellular base station environments. |
| Conversion Gain | 9 dB (downconv.), 12 dB (upconv.) - Reduces need for external IF/LNA stages, simplifying signal chain design and PCB area. |
| Noise Figure (SSB) | 10 dB @ 468 MHz IF - Maintains receiver sensitivity in high-gain, low-noise front-end configurations. |
| LO Drive Level | 0 to +6 dBm - Compatible with low-power synthesizers, eliminating need for LO buffer amplifiers in many designs. |
| LO–RF Isolation | 33 dB (typ.) - Minimizes LO leakage into antenna paths, easing filter requirements and improving spectral purity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF range (1.7–4.2 GHz), higher +25 dBm IP3, but requires +13 dBm LO drive and lacks integrated IF amplifier. | Suitable for ultra-high-linearity receive paths where external IF gain is acceptable and LO power is available. | Select HMC1048LP4E only when IP3 >+24 dBm is mandatory and LO drive headroom exists; HMC622LP4 remains preferred for integrated gain and low-LO-power systems. |
| ADL5802ACPZ-R7 | Lower frequency range (100–6000 MHz), +22 dBm IP3, no integrated LO/IF amps, 16-pin QFN package. | Used in wideband test equipment and software-defined radios where flexibility outweighs integration benefits. | Choose ADL5802ACPZ-R7 for broad frequency coverage and lower cost; HMC622LP4 is superior for compact, high-gain, low-LO-power infrastructure designs. |
Compared with HMC1048LP4E and ADL5802ACPZ-R7, the HMC622LP4 uniquely combines integrated LO/IF amplification, +23 dBm IP3, and +3 dBm LO drive in a 4×4 mm package - making it optimal for space-constrained, power-sensitive wireless infrastructure where gain and linearity must coexist without external active stages.

FAQ
What is the operating temperature range for the HMC622LP4?
The HMC622LP4 is specified for continuous operation from –40°C to +85°C ambient temperature. Junction temperature must not exceed 150°C, and thermal derating begins above 85°C at 14.9 mW/°C. The 67.2 °C/W thermal resistance from junction to ground paddle requires proper PCB copper area and via stitching to maintain reliability under full RF load. This range supports deployment in outdoor base station enclosures and indoor repeater units.
Does the HMC622LP4 require external DC blocking capacitors?
Yes - the HMC622LP4 requires external DC blocking capacitors on the LO (Pin 21), MIXLO (Pin 16), and RF (Pin 3) ports in most configurations. These are necessary because all three ports are DC-coupled and internally biased; omitting them risks DC path disruption or damage from unintended bias currents. Application circuits specify 100 pF capacitors for these positions, sized to pass the full 1.8–3.9 GHz RF band with minimal insertion loss.
Can the HMC622LP4 be used in both upconversion and downconversion modes?
Yes - the HMC622LP4 is explicitly designed for bidirectional operation. In downconversion mode, RF serves as input and IFOUT as output (9 dB gain, +23 dBm IP3). In upconversion mode, IFIN is the input and RF becomes the output (12 dB gain). Pin functions remain identical; only external matching and biasing differ per mode. Evaluation boards 119244 (upconverter) and 119328 (downconverter) validate both configurations.
What is the recommended power supply configuration for the HMC622LP4?
The HMC622LP4 requires two independent +5 V supplies: VddIF (Pin 13) for the IF amplifier and BIAS (Pin 18) for the LO amplifier. Total supply current is 175–220 mA. Each supply must be decoupled with a choke inductor and multiple bypass capacitors (100 pF, 1000 pF, and 2.2 μF) as shown in the application circuits. Separating the supplies prevents LO amplifier noise from modulating the IF amplifier output and ensures stable gain across temperature.
Is the HMC622LP4 pin-compatible with the HMC622LP4E?
Yes - the HMC622LP4 and HMC622LP4E share identical pinout, electrical specifications, and mechanical footprint. The sole difference is RoHS compliance: HMC622LP4 uses Sn/Pb lead finish (reflow peak 235°C), while HMC622LP4E uses 100% matte Sn (reflow peak 260°C). Both are MSL1 rated and interchangeable in layout; selection depends solely on environmental compliance requirements and assembly process compatibility.
