Product details
Overview
HMC141LH5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive double-balanced mixer in a hermetic SMT leadless package, operating from 7–14 GHz RF/LO and DC–2 GHz IF. It delivers +20 dBm input IP3, 35 dB LO-to-RF isolation, and 12 dB typical conversion loss, enabling high-dynamic-range upconversion or downconversion in military radar and telecom infrastructure.
For engineers reviewing the HMC141LH5 datasheet, HMC141LH5 pinout, HMC141LH5 application, or HMC141LH5 equivalent, key selection criteria include RF/LO bandwidth coverage (7–14 GHz), hermetic SMT packaging for space-grade reliability, LO drive sensitivity (+15 dBm typical), and MIL-PRF-38535 Class B/S screening availability.
Technical Context
The HMC141LH5 implements a passive diode/balun architecture with monolithic GaAs MMIC integration, delivering exceptional amplitude and phase balance across RF, LO, and IF ports. This enables high LO/RF (35 dB typ.) and LO/IF (34 dB typ.) isolations without external baluns.
It operates as a broadband, bidirectional mixer-supporting both upconversion and downconversion-with DC-coupled IF and AC-coupled 50 Ω-matched RF/LO ports. Its +15 dBm LO drive requirement and +13 dBm absolute max RF/IF input define its use in high-linearity signal chains where active mixers saturate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 7–14 GHz - Covers full X-band and lower Ku-band; supports wideband radar and satellite uplink/downlink. |
| IF Frequency Range | DC–2 GHz - Enables baseband and low-IF architectures including zero-IF receivers and direct-conversion transmitters. |
| Input IP3 | +20 dBm typ. - Supports high-signal environments like ECM and multi-carrier cellular base stations without intermodulation distortion. |
| Conversion Loss | 12 dB typ. - Defines system noise figure impact; requires low-noise amplification post-mixer in receiver chains. |
| LO to RF Isolation | 35 dB typ. - Reduces LO leakage into antenna paths, easing filtering requirements in full-duplex systems. |
| Operating Temperature | −40°C to +85°C - Qualified for extended industrial and military platforms without derating. |
| Package Size | 25 mm² hermetic ceramic - Enables high-reliability surface-mount assembly compatible with automated reflow processes. |
Pinout & Package
Hermetic SMT leadless ceramic package (25 mm²), gold-plated Kovar/ceramic body with solderable ground paddle and perimeter ground leads. All ground pins (1, 3, 4, 6, 7, 9–12) and package base must be soldered directly to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7, 9–12 | GND | RF/DC ground connection points; mandatory low-inductance soldering to PCB ground plane for optimal isolation and thermal dissipation. |
| 2 | RF | AC-coupled 50 Ω matched port (7–14 GHz); requires external DC blocking if used in upconverter configuration with DC-coupled LO. |
| 5 | IF | DC-coupled port; supports DC–2 GHz operation but limited to ±2 mA current to prevent die damage. |
| 8 | LO | AC-coupled 50 Ω matched port (7–14 GHz); requires +15 dBm drive for specified performance; sensitive to impedance mismatch. |
Key Features
| Feature | Design Value |
|---|---|
| Passive diode/balun topology | Eliminates DC bias and active device nonlinearities, enabling stable performance over temperature and lifetime. |
| Hermetic ceramic SMT package | Provides moisture resistance and long-term reliability in space, avionics, and harsh-environment deployments. |
| MIL-PRF-38535 screening option | Enables Class B or S qualification for mission-critical defense and aerospace applications requiring traceable lot control. |
| High unit-to-unit consistency | MMIC fabrication ensures <±0.5 dB conversion loss variation across production lots-critical for phased-array calibration. |
| ESD robustness (HBM Class 1A) | Withstands ≥250 V HBM ESD events, reducing handling risk during manual assembly and test. |
Applications
| Telecom Infrastructure | Military Radar |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC774ALC3 | Wider RF/LO range (6–22 GHz), higher conversion loss (13.5 dB typ.), same hermetic SMT package. | Better suited for Ka-band test equipment; less optimal for X-band radar due to higher loss and reduced IP3 (+18 dBm). | Select when broader frequency coverage outweighs need for maximum linearity in X-band. |
| QPC1006 | Lower frequency range (2–8 GHz), GaN-based, +24 dBm IP3, non-hermetic plastic QFN. | Targeted at commercial 5G FR1 infrastructure; lacks MIL screening and DC-coupled IF capability. | Choose for cost-sensitive, high-volume terrestrial applications where hermeticity and DC IF are not required. |
Compared with HMC774ALC3 and QPC1006, the HMC141LH5 uniquely balances X-band performance, hermetic reliability, DC-coupled IF flexibility, and MIL-qualified screening-making it the preferred choice for defense radar and space transponders where unit consistency and environmental resilience are non-negotiable.

FAQ
What is the recommended LO drive level for optimal performance of the HMC141LH5?
The HMC141LH5 achieves specified conversion loss, IP3, and isolation at +15 dBm LO drive. Performance degrades below +13 dBm (increased conversion loss) and above +20 dBm (risk of compression). The HMC141LH5 datasheet specifies all electrical characteristics measured at +15 dBm LO drive, making it the design center point for repeatable system calibration.
Can the HMC141LH5 be used for zero-IF (direct-conversion) receiver designs?
Yes-the HMC141LH5 supports DC-coupled IF operation from DC to 2 GHz, enabling true zero-IF architectures. However, the IF port must not source or sink more than ±2 mA DC current; exceeding this limit risks die failure. For DC-coupled use, ensure external bias networks comply with this constraint.
Is the HMC141LH5 pin-compatible with other Hittite mixer variants like HMC142LH5?
No-HMC142LH5 is a different part with distinct pinout, frequency range (6–18 GHz), and internal architecture. The HMC141LH5 has a unique 12-pin leadless layout with specific ground pin assignments (pins 1,3,4,6,7,9–12) and no documented pin compatibility with HMC142LH5 or other Hittite mixers.
Does the HMC141LH5 require external baluns or matching components?
No-the HMC141LH5 integrates passive diode/balun circuitry monolithically. Its RF and LO ports are internally matched to 50 Ω across 7–14 GHz, and the IF port is DC-coupled. Only standard RF layout practices (50 Ω traces, solid ground plane, grounded package base) are required; no external baluns, transformers, or matching networks are needed.
What is the thermal resistance and power dissipation limit of the HMC141LH5?
The HMC141LH5 has a channel-to-package thermal resistance of 101.7 °C/W. At +85 °C ambient, its continuous power dissipation is 640 mW, derating linearly by 9.83 mW/°C above that temperature. This defines the maximum allowable RF/LO/IF power sum under steady-state conditions to avoid exceeding 150 °C channel temperature.
