RoHS Compliant 5x5 mm SMT Package

The HMC567LC5 is a compact GaAs MCM I/Q downconverter in a leadless RoHS compliant SMT package. This device provides a small signal conversion gain of 10 dB with a noise figure of 2.5 dB and 35 dB of image rejection across the frequency band. The HMC567LC5 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. I and Q mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The HMC567LC5 is a much smaller alternative to hybrid style image reject mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface mount manufacturing techniques.
