Product Summary

The HMC908LC5 is a compact GaAs MCM I/Q downconverter in a leadless RoHS compliant SMT ceramic package. This device provides a small signal conversion gain of 11 dB with a noise figure of 2.2 dB and 25 dB of image rejection. The HMC908LC5 utilizes an LNA followed by an image reject mixer which is driven by an LO buffer amplifier. The image reject mixer eliminates the need for a filter following the LNA, and removes thermal noise at the image frequency. The applications of the HMC908LC5 are Point-to-Point and Point-to-Multi-Point Radio, Military Radar, EW & ELINT, Satellite Communications, Maritime & Mobile Radio.
