Multi-chip receive module for a wide-band X-band dual-beam phased array communication antenna

A wide-bandwidth X-band receive module has been developed to support a phased array communication antenna with dual-beam operation. The module utilizes four GaAs MMICs, a single low-temperature-cofired-ceramic (LTCC) substrate, blind-mate connectors, and a custom miniature DC/control 8-pin connector to address the electrical and packaging requirements. A typical module exhibited 3.5 dB noise figure, 23 dB of gain, 0.5 dB RMS amplitude error, and 7/spl deg/ RMS phase error from 7.0-10.0 GHz.
