Product Details
The HMC951A is a compact gallium arsenide (GaAs), monolithic microwave integrated circuit (MMIC), in-phase quadrature (I/Q) downconverter in a RoHS compliant package that operates from 5.6 GHz to 8.6 GHz. This device provides a small signal conversion gain of 13 dB with a noise figure of 2 dB and an image rejection of 32 dBc. The HMC951A uses a low noise amplifier (LNA) followed by an image mixer that is driven by a local oscillator (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 IF1 and IF2 mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The I/Q mixer topology reduces the need for filtering of unwanted sideband. The HMC951A is a smaller alternative to hybrid style, single sideband (SSB) downconverter assemblies, and it eliminates the need for wire bonding by allowing the use of surface-mount manufacturing techniques.
The HMC951A is available in 4 mm × 4 mm, 24-lead lead frame chip scale package (LFCSP) and operates over the −40°C to +85°C temperature range. An evaluation board for the HMC951A is also available upon request.
