HMC445LP4ETR

Overview

The HMC445LP4ETR is an active miniature x16 frequency multiplier utilizing InGaP GaAs HBT technology. It operates within a 9.9 GHz to 11.2 GHz output frequency range, delivering +7 dBm output power with sub-harmonic suppression exceeding 25 dBc and single-sideband phase noise of -130 dBc/Hz. The device requires a single 5V supply at 78 mA current draw. Packaged in a 24-lead 4x4 mm leadless surface mount QFN format, it supports applications including fiber optic systems, point-to-point radios, and military radar.

Procurement Notes

Verify the specific suffix 'ETR' against official Analog Devices documentation to confirm reel packaging and tape-and-reel specifications. Ensure compatibility with standard SMT reflow profiles for 24-lead QFN packages. Cross-reference the datasheet revision history for any updates regarding thermal characteristics or pinout configurations prior to final procurement approval.

Selection Notes

Select this component when designing X-band circuits requiring high-frequency generation from lower input sources. The integrated active design eliminates external filtering complexity while maintaining compact footprint. Evaluate thermal management requirements due to the dense 4x4 mm package layout and ensure input drive levels align with the specified operational parameters for optimal efficiency.

Part Context

This part belongs to the HMC445 series of active frequency multipliers manufactured by Analog Devices Inc. It shares architectural similarities with other members of the family but is distinguished by its specific output frequency range and packaging variant. The ETR suffix indicates a specific reel-based packaging configuration intended for automated surface-mount assembly processes.
