Product details
Overview
HMC144LH5 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer operating from 6 to 20 GHz, designed for upconversion or downconversion with no external bias or components required. It delivers typical conversion loss of 11 dB, input IP3 of +24 dBm, LO/RF isolation of 35 dB, and DC–3 GHz IF bandwidth in a hermetic SMT package-enabling high-reliability RF front-ends in radar and test instrumentation.
For engineers reviewing the HMC144LH5 datasheet, HMC144LH5 pinout, HMC144LH5 application, or HMC144LH5 equivalent, key selection criteria include its broadband 6–20 GHz RF/LO range, LO drive sensitivity (+13 to +20 dBm), DC-coupled IF port, hermetic ceramic/Kovar SMT package, and MIL-PRF-38535 screening availability for space/military use.
Technical Context
The HMC144LH5 integrates on-chip baluns to enable true double-balanced operation across 6–20 GHz, eliminating external hybrids or transformers. Its monolithic GaAs design ensures consistent conversion loss and isolation over temperature (−40°C to +85°C) and production lots without DC biasing.
It operates as a passive mixer with AC-coupled 50 Ω RF and LO ports, a DC-coupled IF port rated for ±2 mA, and requires no external matching or bias circuitry-making it suitable for compact, high-frequency transceivers where layout simplicity and repeatability are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Narrower RF/LO range (4–12 GHz); higher conversion loss (12.5 dB typ.); same hermetic SMT package. | Better suited for lower-frequency radar and SATCOM terminals below 12 GHz. | Select when cost or legacy design compatibility outweighs need for 12–20 GHz coverage. |
| QPC1006 | Wider IF bandwidth (DC–6 GHz); GaN-based; higher P1dB (+17 dBm); non-hermetic QFN package. | Preferred for high-power, wideband test equipment requiring extended IF digitization bandwidth. | Choose only if hermeticity and MIL screening are not required and higher power handling is critical. |
Compared with HMC1048LP3E and QPC1006, the HMC144LH5 uniquely balances ultra-wide 6–20 GHz RF coverage, hermetic reliability, and DC-coupled IF capability-making it the only option qualified for space-grade, zero-IF radar receivers demanding both bandwidth and lifetime assurance.

FAQ
What is the recommended LO drive level for optimal performance of the HMC144LH5?
The HMC144LH5 achieves best conversion loss (11 dB typ.) and IP3 (+24 dBm) at LO = +20 dBm. Performance remains usable from +13 to +20 dBm, with conversion gain dropping ~0.5 dB per dB decrease in LO power. Drive above +20 dBm yields diminishing returns and risks exceeding absolute max rating of +27 dBm. Always verify LO drive with calibrated source in final HMC144LH5 design.
Can the HMC144LH5 be used for zero-IF (direct-conversion) receiver applications?
Yes-the HMC144LH5 supports zero-IF operation due to its DC-coupled IF port and DC–3 GHz bandwidth. However, the IF port must not source or sink more than ±2 mA to avoid die damage. For true DC operation, ensure external DC bias networks comply with this limit. The HMC144LH5 has been validated in I/Q demodulator designs for radar and satellite receivers.
Is the HMC144LH5 pin-compatible with other Hittite double-balanced mixers like the HMC1048LP3E?
No-HMC144LH5 uses a 12-pin hermetic SMT package with specific pin assignments (e.g., IF on Pin 5, LO on Pin 8), while HMC1048LP3E uses a 3×3 mm LP3E package with different pinout and ground configuration. PCB redesign is required for substitution. Always consult respective package drawings before layout reuse.
Does the HMC144LH5 require external DC blocking capacitors on RF or LO ports?
No-the HMC144LH5 integrates internal AC coupling on RF (Pin 2) and LO (Pin 8) ports, both matched to 50 Ω. External DC blocks are unnecessary and may degrade broadband match. Only the IF port (Pin 5) is DC-coupled; add series capacitor only if DC operation is not needed and IF bandwidth extends beyond 3 GHz.
What screening levels are available for the HMC144LH5, and how do they affect procurement?
HMC144LH5 is available with MIL-PRF-38535 Class B (standard reliability) and Class S (space-level) screening, including lot traceability, extended burn-in, and parametric testing. Class S units require longer lead times and minimum order quantities; Aetrix Electronics maintains stock of Class B and coordinates special orders for Class S with Analog Devices' qualified sources.
