Product details
Overview
HMC171C8 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in a non-hermetic ceramic SMT package, operating 7–10 GHz RF/LO with DC–2 GHz IF bandwidth, 9 dB typical conversion loss, 32 dB LO-to-RF isolation, and +16 dBm input IP3 - used in microwave point-to-point radios and 5.8 GHz ISM band up/downconversion.
For engineers reviewing the HMC171C8 datasheet, HMC171C8 pinout, HMC171C8 application, or HMC171C8 equivalent, key selection criteria include its passive diode/balun architecture, no-DC-bias operation, surface-mount compatibility, high LO/RF isolation, and suitability for compact RF front-ends requiring stable wideband mixing performance.
Technical Context
The HMC171C8 implements a passive GaAs MMIC double-balanced topology using integrated baluns to achieve high port-to-port isolation and unit-to-unit consistency. Its RF and LO ports operate over 7–10 GHz, while the IF port supports DC–2 GHz, enabling flexible use as upconverter, downconverter, or biphase modulator.
No external DC bias is required; operation relies solely on LO drive (typ. +10 dBm). Noise figure equals conversion loss (~9 dB), and high linearity is enabled by +16 dBm input IP3 and +10 dBm 1 dB compression point - critical for handling large-signal interferers in dense RF environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Freq Range | 7.0–10.0 GHz - defines usable band for microwave radio links and ISM-band transceivers |
| IF Bandwidth | DC–2 GHz - supports baseband and low-IF architectures without external filtering |
| Conversion Loss | 9 dB typ. - sets minimum gain budget for receiver chain or transmit path loss compensation |
| LO-to-RF Isolation | 32 dB typ. - reduces LO leakage into antenna path, easing filter requirements |
| Input IP3 | +16 dBm typ. - enables robust operation in presence of strong adjacent-channel signals |
| 1 dB Compression | +10 dBm typ. - indicates maximum usable RF input level before distortion dominates |
| Operating Temp | −55°C to +85°C - qualified for industrial and outdoor wireless infrastructure |
Pinout & Package
Package: 8-lead non-hermetic ceramic SMT (white alumina body, copper leadframe, electrolytic gold plating); dimensions per outline drawing - requires full ground paddle soldering and via-stitched PCB grounding per RF design best practices.

| 5 | RF Input | 7–10 GHz RF signal port; matched to 50 Ω; requires microstrip impedance control |
| 6 | LO Input | 7–10 GHz local oscillator port; +10 dBm drive required; sensitive to return loss |
| 7 | IF Output | DC–2 GHz differential IF output; requires balun or transformer for single-ended interface |
| 8 | RF/LO Common Ground Reference | Shared reference for RF and LO balun center-taps; connects internally to ground paddle |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC171LP3E | Same die, 3 mm × 3 mm QFN package with exposed paddle; higher thermal conductivity; requires different footprint | Preferred for thermally constrained designs needing >100 mW dissipation; not drop-in compatible | Select when thermal management outweighs layout reuse; verify ground paddle soldering per JEDEC MO-220 |
| ADL5801ACPZ-R7 | Active SiGe mixer; +5 V bias required; 7–1300 MHz IF; 10.5 dB conversion loss; lower IP3 (+11 dBm) | Suitable for wideband IF processing but lacks DC-coupled IF and high-frequency LO drive tolerance | Choose only if active gain, lower LO drive, or sub-GHz IF flexibility are prioritized over passive simplicity and linearity |
Compared with HMC171C8, HMC171LP3E offers superior thermal performance in a modern QFN, while ADL5801ACPZ-R7 trades passive robustness for active gain and wider IF range - neither is pin-compatible, and both require PCB redesign and bias circuit changes.

FAQ
What is the operating frequency range of the HMC171C8?
The HMC171C8 operates with RF and LO frequencies from 7.0 to 10.0 GHz, and supports an IF bandwidth from DC to 2.0 GHz. This makes it suitable for microwave radio links and ISM-band systems. The HMC171C8 does not require DC bias and delivers consistent performance across this full band when driven with +10 dBm LO power.
Does the HMC171C8 require external DC bias?
No, the HMC171C8 is a passive GaAs MMIC double-balanced mixer and requires no external DC bias. It operates solely on LO drive (typically +10 dBm). This eliminates bias networks, reduces component count, and improves reliability - a key advantage of the HMC171C8 in space-constrained RF designs.
What is the conversion loss and noise figure of the HMC171C8?
The HMC171C8 has a typical conversion loss of 9 dB and a single-sideband noise figure equal to that loss (9 dB). These values are measured at +25°C with +10 dBm LO drive. Because the HMC171C8 is passive, its noise figure tracks conversion loss directly - critical for predicting overall receiver sensitivity in systems using the HMC171C8.
What package type does the HMC171C8 use, and how should it be mounted?
The HMC171C8 uses an 8-lead non-hermetic ceramic SMT package with a grounded metal paddle. All ground leads and the exposed paddle must be soldered to the PCB RF ground plane using multiple thermal vias. Per datasheet note, improper grounding degrades isolation and conversion loss - correct mounting is essential for achieving specified HMC171C8 performance.
Is the HMC171C8 still in active production?
The HMC171C8 is marked OBSOLETE in official documentation, but Aetrix Electronics maintains traceable inventory and legacy supply channels. While not actively manufactured, the HMC171C8 remains available for design continuity and repair scenarios - with full documentation, evaluation board support (PCB #107214), and technical validation data for the HMC171C8 preserved.
