HMC570LC5TR

Overview

The HMC570LC5TR is a GaAs MMIC I/Q downconverter designed for surface-mount applications. It operates within a radio frequency range of 17 GHz to 21 GHz, with an intermediate frequency span from 0 Hz to 3.5 GHz and a local oscillator frequency range of 7 GHz to 12 GHz. The device provides a gain of 10 dB, a P1dB compression point of -4 dBm, and a noise figure of 3 dB. It functions on a single 3.5 V supply, drawing 125 mA of current. Packaged in an LFCSP-32 leadless SMT format, it supports an operating temperature range from -55°C to +85°C.

Feature Summary
