Product details
Overview
HMC329LM3TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced passive mixer for 26–40 GHz RF/LO and DC–8 GHz IF operation, requiring no DC bias and delivering 10 dB typical conversion loss, +19 dBm input IP3, and 35 dB LO/RF isolation. It serves as upconverter or downconverter in millimeter-wave transceivers.
For engineers reviewing the HMC329LM3TR datasheet, HMC329LM3TR pinout, HMC329LM3TR application, or HMC329LM3TR equivalent, this page provides verified RF mixer specifications, thermal performance across –40°C to +85°C, absolute maximum ratings, and layout-critical grounding requirements for 2.4 mm connector or GSG probe evaluation.
Technical Context
The HMC329LM3TR employs on-chip baluns to achieve high LO/RF (37 dB typ), LO/IF (35 dB typ), and RF/IF (28 dB typ) isolations-enabling clean signal translation without external filtering. Its passive architecture eliminates DC bias circuitry and supports both upconversion and downconversion modes with identical RF/LO port symmetry.
Designed for surface-mount integration in 50 Ω microstrip/CPWG environments, the device operates with +13 dBm LO drive and delivers stable conversion gain across temperature (±1.5 dB variation from –40°C to +85°C at 31 GHz). Spurious output suppression exceeds 67 dBc for m=2,n=1 and m=3,n=0 products under two-tone –10 dBm RF input.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IF Bandwidth | DC–8 GHz - supports baseband I/Q modulation and wideband IF digitization |
| Conversion Loss | 10 dB typical - defines minimum LNA gain required before mixer to maintain system NF |
| Input IP3 | +19 dBm typical - determines third-order intermodulation headroom in multi-carrier systems |
| LO/RF Isolation | 37 dB typical - reduces LO leakage into antenna path, easing filter design in TDD systems |
| Operating Temperature | –40°C to +85°C - validated for outdoor microwave backhaul enclosures without active cooling |
| ESD Sensitivity | HBM Class 1B (≤250 V) - mandates strict handling protocols during SMT assembly |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar millimeter-wave mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (10–40 GHz), higher conversion loss (12 dB typ), requires +17 dBm LO drive | Better suited for sub-26 GHz legacy systems needing broader frequency coverage | Select when IF bandwidth <4 GHz suffices and LO drive >+15 dBm is available |
| Qorvo QM11020 | Higher IF bandwidth (DC–12 GHz), +21 dBm IP3, but narrower RF/LO range (24–34 GHz) | Optimized for 5G FR2 deployments where upper band edge is ≤34 GHz | Select when system IF processing demands >8 GHz bandwidth and RF band fits within 24–34 GHz |
Compared with HMC1048LP3E and QM11020, the HMC329LM3TR offers the narrowest RF/LO band (26–40 GHz) but best balance of conversion loss (10 dB), IP3 (+19 dBm), and LO drive (+13 dBm) specifically for 38 GHz fixed wireless and SATCOM receive chains.

FAQ
What is the recommended LO drive level for optimal performance of the HMC329LM3TR?
The HMC329LM3TR achieves best conversion loss (10 dB typ), IP3 (+19 dBm), and isolation (>35 dB) at +13 dBm LO drive. Performance degrades above +15 dBm due to compression, and below +11 dBm due to increased noise figure. The datasheet specifies all key parameters at +13 dBm, making it the design center for HMC329LM3TR applications.
Can the HMC329LM3TR be used for DC-coupled IF operation?
Yes, the HMC329LM3TR IF port is DC-coupled, but the device must not source or sink more than ±2 mA DC current at Pin 5, or permanent malfunction may occur. For true DC–8 GHz operation, ensure external biasing networks comply with this current limit. If DC blocking is preferred, add a series capacitor sized for the lowest IF frequency.
Is the HMC329LM3TR pin-compatible with other LM3-package mixers like the HMC1117LM3?
No, the HMC329LM3TR is not pin-compatible with HMC1117LM3. While both use the LM3 package, HMC329LM3TR has six defined terminals (Pins 1–3 N/C, 4 RF, 5 IF, 6 LO), whereas HMC1117LM3 uses a different pin assignment including dedicated RF/LO/IF ports and ground vias. Layout reuse is not possible without redesign.
What is the maximum allowable reflow temperature for the HMC329LM3TR LM3 package?
The HMC329LM3TR LM3 package is qualified for peak reflow temperatures up to 235°C for ≤15 seconds, per JEDEC J-STD-020. Exceeding this profile risks delamination or metallization damage. The recommended profile includes controlled ramp rates, preheat hold, and flux activation time-details are in the HMC329LM3TR application note on SMT attachment technique.
Does the HMC329LM3TR require external matching components for 50 Ω operation?
No, the HMC329LM3TR RF, LO, and IF ports are internally matched to 50 Ω across their specified bands (26–40 GHz for RF/LO; DC–8 GHz for IF). No external matching networks are needed-only proper PCB layout (microstrip/CPWG with controlled impedance and solid ground) is required to maintain performance.
