HMC908ALC5 General Description

The HMC908A is a compact, gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), inphase/quadrature (I/Q) downconverter in a leadless, RoHS compliant ceramic leadless chip carrier. This device provides a small signal conversion gain of 11 dB with a noise figure of 2 dB and 25 dB of image rejection at 100 MHz. The HMC908A utilizes a low noise amplifier (LNA) followed by an image rejection mixer that is driven by a local oscillator (LO) buffer amplifier. The image rejection 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 HMC908A is a much smaller alternative to hybrid style image rejection mixer downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.
