HMU16GM-45/883

Specialty Logic Overview

The Harris Corporation HMU16GM-45/883 is a high-reliability microwave monolithic integrated circuit (MMIC) amplifier. It operates within the frequency range of 12.4 to 18 GHz, providing a typical small-signal gain of 16 dB with an output power of 1 W at the 1 dB compression point. The device features a hermetic surface-mount package designed for harsh environments and meets MIL-PRF-38534 Class K specifications. Key electrical characteristics include a noise figure of approximately 4.5 dB and input/output return losses exceeding 10 dB. It utilizes a positive supply voltage and incorporates internal biasing for simplified integration into radar and electronic warfare systems.

Specialty Logic Procurement Notes

Verify the specific suffix code against the manufacturer's current datasheet to confirm pinout compatibility and exact gain tolerance. Ensure that the procurement source provides a Certificate of Conformance (CoC) traceable to MIL-PRF-38534 Class K standards. Request full lot traceability documentation and material declarations to satisfy defense contract requirements before finalizing acquisition.

Specialty Logic Selection Notes

Select this component when a wide X-band operational bandwidth is required alongside high output power density in a compact form factor. Compare the specified noise figure and gain flatness against system link budget requirements. Evaluate the thermal resistance parameters relative to the available printed circuit board copper area for adequate heat sinking. Confirm that the supply voltage and bias current limits align with the system's power management architecture.

Specialty Logic Part Context

This MMIC belongs to the broader family of Harris Microwave Semiconductor high-power amplifiers, now part of L3Harris Technologies. These devices are engineered for military aerospace applications requiring extreme reliability. The /883 designation indicates compliance with MIL-STD-883 testing standards for microelectronics. This series represents a transition from older TO-can packages to modern surface-mount technologies for improved assembly yield.

Specialty Logic Replacement Considerations

Direct replacements may include the Harris HMPA-0007 or equivalent L3Harris models within the same frequency band. Verify that substitute parts match the critical dimensions and pin assignments. Cross-reference the replacement datasheet for any changes in maximum ratings or thermal characteristics to ensure system safety.
