Exposed paddle, 4 mm 4 mm, 24-lead, LFCSP APPLICATIONS Point to point and point to multipoint radios Military radars, electronic warfare, and electronic intelligence Satellite communications Sensors GENERAL DESCRIPTION The HMC951A is a compact gallium arsenide (GaAs), select the required sideband. The I/Q mixer topology reduces monolithic microwave integrated circuit (MMIC), in-phase the need for filtering of unwanted sideband. The HMC951A quadrature (I/Q) downconverter in a RoHS compliant package is a smaller alternative to hybrid style, single sideband (SSB) that operates from 5.6 GHz to 8.6 GHz. This device provides a downconverter assemblies, and it eliminates the need for wire small signal conversion gain of 13 dB with a noise figure of 2 dB bonding by allowing the use of surface-mount manufacturing and an image rejection of 32 dBc. The HMC951A uses a low noise techniques. amplifier (LNA) followed by an image mixer that is driven by a The HMC951A is available in 4 mm 4 mm, 24-lead lead local oscillator (LO) buffer amplifier. The image reject mixer frame chip scale package (LFCSP) and operates over the eliminates the need for a filter following the LNA and removes 40C to +85C temperature range. An evaluation board for thermal noise at the image frequency. The IF1 and IF2 mixer the HMC951A is also available upon request. outputs are provided and an external 90 hybrid is needed to Rev.
