HMC144LH5

RF Mixers Overview

The HMC144LH5 is a GaAs MMIC double-balanced mixer housed in a hermetic SMT leadless package, functioning as an upconverter or downconverter from 6 to 20 GHz. It features broadband operation with on-chip baluns, requiring no external components or DC bias. Key electrical parameters include an input IP3 of +24 dBm, LO/RF isolation of 35 dB, and an IF bandwidth from DC to 3 GHz. The device supports surface mount manufacturing techniques and operates within a temperature range of -40°C to 85°C, with a maximum power dissipation of 640 mW.

RF Mixers Procurement Notes

Verify the specific screening level required for your application, as the HMC144LH5 is available with screening to MIL-PRF-38535 Class B or S. Ensure that the procurement documentation explicitly confirms the hermetic seal integrity and GaAs MMIC construction. Confirm that the supplier provides traceability to the original manufacturer specifications to guarantee consistent performance metrics such as isolation and IP3 levels.

RF Mixers Selection Notes

Select the HMC144LH5 when designing systems requiring reliable frequency conversion between 6 and 20 GHz without the complexity of discrete diode mixers. Its hermetic packaging makes it suitable for harsh environments where standard plastic packages may fail. Consider this component for applications demanding high isolation and stable conversion loss over multiple production runs, particularly in military or space contexts.

RF Mixers Part Context

The HMC144LH5 is part of the Analog Devices (formerly Hittite Microwave) portfolio of RF mixers. It serves as a robust alternative to hybrid diode mixers, offering improved reliability through its monolithic microwave integrated circuit design. The component is designed for high-reliability sectors, leveraging GaAs technology to provide consistent performance in demanding upconversion and downconversion tasks.
