HMC6147ALC5ATR

Overview

The HMC6147ALC5ATR is a GaAs MMIC IQ downconverter from Analog Devices, operating in the 37 GHz to 44 GHz RF range. It features an LO frequency range of 16.5 GHz to 22 GHz and an IF bandwidth from 0 Hz to 4 GHz. Key electrical parameters include a gain of 13 dB, a P1dB compression point of 1 dBm, and a noise figure of 3.5 dB. The device requires a single 3 V supply with current consumption of 75 mA or 150 mA. It is housed in a QFN-EP-16 (CSMD-16) surface-mount package.

Feature Summary

• Integrates I/Q demodulation for direct conversion applications
• Utilizes GaAs technology for high-frequency performance
• Supports wideband intermediate frequency output up to 4 GHz

Applications

• Radar systems
• Point-to-point microwave links
• Satellite communication terminals

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm lot traceability and RoHS compliance status prior to integration. Note that availability may be limited; check current stock levels and lead times with suppliers. Ensure proper ESD handling procedures are followed during storage and assembly due to moisture sensitivity classification.

Selection Notes

Select this component for applications requiring low-noise downconversion in the Ka-band spectrum. Evaluate thermal management requirements given the 1.6 W power dissipation. Ensure local oscillator signals fall within the 16.5–22 GHz range. Consider the QFN-16 footprint for PCB layout constraints. Compare against alternative MMICs if specific gain or linearity targets differ significantly.
