Product details
Overview
HMC402MS8 from Analog Devices (formerly Hittite Microwave) is a passive GaAs MMIC mixer optimized for high-linearity RF front-ends in 1.8–2.2 GHz infrastructure applications. It delivers +31 dBm input IP3 (downconversion), 8.5 dB typical conversion loss, and operates with +17 dBm LO drive-enabling robust GSM/UMTS/PCS transceivers without external bias or components.
For engineers reviewing the HMC402MS8 datasheet, HMC402MS8 pinout, HMC402MS8 application, or HMC402MS8 equivalent, key selection criteria include its high-side LO architecture, MSOP8 footprint (14.8 mm²), DC-coupled RF/IF ports, and absence of DC bias requirements-critical for compact, low-power wireless base station and repeater designs.
Technical Context
The HMC402MS8 is a single-ended passive FET mixer using GaAs Schottky diode topology, configured for high-side LO injection (LO = RF + IF). Its broadband IF response (DC–500 MHz) supports both upconversion and downconversion with fixed 50 Ω RF/LO port matching across 1.8–2.2 GHz.
It achieves high dynamic range via optimized gate geometry and monolithic layout, delivering +21 dBm input P1dB and maintaining 24–30 dB LO-to-RF isolation. No external DC blocking or biasing is required-RF and IF ports are DC-coupled, while the LO port is AC-coupled and 50 Ω matched.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 1.8–2.2 GHz - Covers full PCS 1900 and UMTS Band I (2100 MHz) operating bands. |
| LO Frequency Range | 1.85–2.53 GHz - Supports high-side LO injection with ≥300 MHz IF offset. |
| IF Frequency Range | DC–500 MHz - Enables direct-baseband and low-IF architectures without external filtering. |
| Input IP3 (Downconv.) | +31 dBm @ +17 dBm LO - Enables handling of strong interferers in dense cellular environments. |
| Conversion Loss | 8.5 dB typical - Defines signal path attenuation; requires minimal gain compensation in receiver chain. |
| LO–RF Isolation | 24–30 dB - Reduces LO leakage into antenna path, easing filter requirements in TDD systems. |
| 1 dB Compression (P1dB) | +21 dBm - Sets maximum usable RF input level before distortion dominates. |
Pinout & Package
Package: MSOP-8 (Mini Small Outline Package), 3.0 × 3.0 × 1.1 mm body, exposed paddle, MSL1, Sn/Pb lead finish. Footprint area: 14.8 mm².
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | AC-coupled 50 Ω input; requires external DC blocking if source has non-zero DC potential. |
| 2, 4 | N/C | No internal connection; must remain unconnected per design. |
| 3, 6, 7 | GND | RF ground terminals; must be soldered directly to PCB ground plane with low-inductance vias. |
| 5 | IF Port | DC-coupled output/input; supports DC–500 MHz; current-limited to ±40 mA. |
| 8 | RF Port | DC-coupled 50 Ω RF interface; matched across full 1.8–2.2 GHz band. |
Key Features
| Feature | Design Value |
|---|---|
| No external bias or components required | Eliminates DC power supply, bias tees, and matching networks-reducing BOM count and board area. |
| Ultra-small MSOP8 footprint (14.8 mm²) | Enables dense RF module layouts in space-constrained small-cell and repeater PCBs. |
| +31 dBm input IP3 at +17 dBm LO | Outperforms many active mixers in linearity while avoiding DC power and noise penalties. |
| DC-coupled RF and IF ports | Supports zero-IF and low-IF receivers without series capacitors or high-pass constraints. |
| High-side LO architecture | Simplifies LO filtering by placing image band far from RF band-reducing pre-mixer filter complexity. |
Applications
| UMTS Base Station Receiver | GSM/EDGE Transmitter |
|---|---|
Use Scenario: Downconverting 2110–2170 MHz UMTS Band I signals to 100–200 MHz IF in macrocell BTS receive chains. IC Role / Device Role / Timing Role: Passive mixer providing RF-to-IF translation with minimal added noise and distortion.

IC Role / Device Role / Timing Role: High-linearity passive mixer used in wideband RF sampling front-end prior to ADC. Use Value: +27 dBm upconversion IP3 and 24–30 dB LO–RF isolation reduce spurious generation in multi-carrier cable spectrum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (1.5–3.5 GHz), higher +34 dBm IP3, but larger 3×3 mm QFN package. | Better suited for multi-band macro base stations requiring broader frequency coverage. | Select when wider RF bandwidth and higher linearity outweigh MSOP8 size constraints. |
| ADL5801ACPZ-R7 | Active double-balanced mixer; requires +5 V bias; 6.5 dB conversion gain; 22 dBm IP3. | Provides gain instead of loss; better for low-NF receiver chains where LO drive is limited. | Choose when system needs conversion gain and can accommodate active bias and higher power consumption. |
Compared with HMC1048LP3E and ADL5801ACPZ-R7, the HMC402MS8 offers the smallest footprint and zero-bias operation-ideal for size- and power-sensitive PCS/UMTS repeaters and small cells-while trading off bandwidth and gain for integration simplicity.

FAQ
What is the recommended LO drive level for optimal performance of the HMC402MS8?
The HMC402MS8 achieves best linearity and conversion loss at +16 to +18 dBm LO drive, with +17 dBm specified as typical. Operating below +16 dBm increases conversion loss and degrades IP3; exceeding +18 dBm risks compression or reliability issues. The HMC402MS8 datasheet confirms this range under TA = 25 °C, IF = 300 MHz, and high-side LO configuration.
Does the HMC402MS8 require external DC biasing or blocking components?
No-the HMC402MS8 is a passive GaAs MMIC mixer requiring no DC bias. RF and IF ports are DC-coupled, while the LO port is AC-coupled and internally matched to 50 Ω. External DC blocking is only needed on the LO line if the source has non-zero DC potential. The HMC402MS8 eliminates all bias tees, resistors, and decoupling networks typically required in active mixers.
Can the HMC402MS8 be used for both upconversion and downconversion?
Yes-the HMC402MS8 supports bidirectional operation. As a passive single-ended mixer, it functions identically in upconversion (IF→RF) and downconversion (RF→IF) modes. Its +27 dBm upconversion IP3 and +31 dBm downconversion IP3 are both specified at +17 dBm LO drive, making the HMC402MS8 suitable for full-duplex transceiver front-ends in TDD systems.
What is the maximum allowable DC current at the IF port of the HMC402MS8?
The HMC402MS8 IF port is rated for ±40 mA DC current. Exceeding this limit may cause permanent damage due to junction overheating. This specification applies regardless of IF frequency or signal level. When using the HMC402MS8 in DC-coupled baseband applications, ensure external circuitry limits current to within this range-verified in the Absolute Maximum Ratings table of the HMC402MS8 datasheet.
Is the HMC402MS8 pin-compatible with the HMC402MS8E variant?
Yes-the HMC402MS8 and HMC402MS8E share identical pinout, package dimensions, and electrical specifications. The only difference is RoHS compliance: HMC402MS8E uses 100% matte tin lead finish and supports 260 °C peak reflow, while HMC402MS8 uses Sn/Pb and 235 °C reflow. Both variants use the same MSOP8 footprint and pin assignments-confirmed in the Package Information section of the HMC402MS8 datasheet.
