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, with +20 dBm input IP3, 35 dB LO-to-RF isolation, and 12 dB typical conversion loss - deployed in military radar up/downconversion stages.
For engineers reviewing the HMC141LH5 datasheet, HMC141LH5 pinout, HMC141LH5 application, or HMC141LH5 equivalent, this page delivers verified RF mixer specifications, validated terminal functions, real-world isolation and linearity metrics, and direct alternatives for telecom infrastructure and space-grade frequency translation designs.
Technical Context
The HMC141LH5 implements a passive diode/balun architecture with monolithic GaAs MMIC fabrication, enabling high unit-to-unit consistency and exceptional port-to-port isolation without active biasing. Its balanced topology suppresses even-order harmonics and LO feedthrough across full RF band.
Designed for surface-mount assembly on RF-optimized PCBs (e.g., Rogers 4350), it requires all ground pins (1,3,4,6,7) and the exposed paddle to be soldered to RF ground, with AC-coupled 50 Ω RF and LO ports and DC-coupled IF port rated for ±2 mA current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 7–14 GHz - supports full-band operation as upconverter or downconverter without external tuning. |
| IF Bandwidth | DC–2 GHz - enables baseband and low-IF architectures including zero-IF receivers. |
| Conversion Loss | 12 dB typ. - defines signal attenuation through mixing path; impacts system noise figure and gain budget. |
| Input IP3 | +20 dBm - indicates high linearity for handling strong interferers in crowded RF environments. |
| LO-to-RF Isolation | 35 dB typ. - minimizes LO leakage into antenna or RF front-end, reducing spurious emissions. |
| Operating Temp. | −40°C to +85°C - qualified for extended industrial and military environmental profiles. |
| ESD Rating | HBM Class 1A - mandates strict ESD handling during assembly due to low-voltage sensitivity. |
Pinout & Package
Hermetic SMT leadless ceramic package (25 mm²), 8-terminal layout with exposed ground paddle; requires full-solder connection of ground pins and paddle to PCB RF ground plane per MIL-PRF-38535 screening guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6, 7 | GND | RF/DC ground terminals - must be soldered to PCB ground plane with multiple vias for low-inductance return path. |
| 2 | RF | AC-coupled 50 Ω RF port - matched across 7–14 GHz; no DC bias required. |
| 5 | IF | DC-coupled IF port - supports DC–2 GHz; limited to ±2 mA current to prevent die damage. |
| 8 | LO | AC-coupled 50 Ω LO port - matched across 7–14 GHz; accepts +13 to +27 dBm drive. |
Key Features
| Feature | Design Value |
|---|---|
| Passive Diode/Balun Architecture | Eliminates DC bias circuitry, reduces power supply complexity, and improves reliability over active mixers. |
| Hermetic Ceramic SMT Package | Enables long-term stability in harsh environments (−40°C to +85°C) and supports MIL-PRF-38535 Class B/S screening. |
| High LO-to-RF Isolation (35 dB) | Reduces need for external LO filtering, simplifying front-end design in radar and ECM systems. |
| Unit-to-Unit Consistency | MMIC process ensures tight parameter distribution - critical for phased-array and multi-channel calibration. |

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 8-pin leadless ceramic package. | Better suited for Ka-band test equipment; less optimal for 7–14 GHz radar where HMC141LH5 offers lower loss. | Select HMC774ALC3 only when extending beyond 14 GHz; retain HMC141LH5 for optimized X-band performance. |
| QPC1006 | Lower frequency range (5–12 GHz), +19 dBm IP3, 30 dB LO-to-RF isolation, QFN-16 package with different pinout. | Targeted at commercial 5G FR1 infrastructure; lacks MIL-PRF-38535 screening and hermetic sealing. | Choose QPC1006 for cost-sensitive terrestrial 5G; prefer HMC141LH5 for defense/space applications requiring reliability and isolation. |
Compared with HMC774ALC3 and QPC1006, the HMC141LH5 delivers superior LO-to-RF isolation and tighter parameter distribution within its native 7–14 GHz band, making it the preferred choice for military radar and space-grade downconverters where spurious suppression and unit consistency are critical.

FAQ
What is the maximum LO drive level supported by the HMC141LH5?
The HMC141LH5 supports a maximum LO drive level of +27 dBm, as specified in its Absolute Maximum Ratings. Operating above this level risks permanent damage to the GaAs diode elements. For optimal linearity and conversion loss, +15 dBm LO drive is recommended per the electrical specifications table, where key parameters like IP3 and isolation are characterized.
Can the HMC141LH5 be used for DC-coupled IF applications?
Yes, the HMC141LH5 IF port (Pin 5) is DC-coupled and supports operation from DC to 2 GHz. However, the device must not source or sink more than ±2 mA of DC current at this port, as exceeding this limit may cause die non-function or failure. External DC blocking is required only if DC operation is unnecessary.
Is the HMC141LH5 pin-compatible with other Hittite mixer packages like the HMC142 or HMC774 series?
No, the HMC141LH5 uses an 8-pin leadless ceramic package with specific pin assignments (e.g., GND on Pins 1,3,4,6,7; RF on Pin 2; IF on Pin 5; LO on Pin 8). The HMC142 uses a different outline and pin count, and the HMC774ALC3 shares the same footprint but differs in internal matching and biasing - neither qualifies as pin-compatible without circuit redesign.
What thermal management is required for the HMC141LH5 at full power dissipation?
The HMC141LH5 has a thermal resistance of 101.7 °C/W (channel to package bottom). At its maximum continuous dissipation of 640 mW (at 85 °C ambient), junction temperature rises ~65 °C above ambient - requiring a low-thermal-resistance PCB layout: full-solder connection of all ground pins and the exposed paddle to a solid copper ground plane with ≥6 thermal vias underneath the package.
Does the HMC141LH5 require external baluns or matching networks for 50 Ω operation?
No, the HMC141LH5 integrates on-die baluns and is internally matched to 50 Ω at both RF (Pin 2) and LO (Pin 8) ports across 7–14 GHz. Only standard 50 Ω microstrip routing is needed; no external baluns, transformers, or matching components are required for nominal operation - simplifying layout and reducing insertion loss.
