Broadband 2W Transmit/Receive Module using Indigenous GaAs & GaN MMICs

This paper presents the design, fabrication and test results of a highly integrated wideband 2W 6-18GHz T/R module built using the MMICs designed in house. Both GaAs & GaN technologies were employed for the designs; all the low power amplifiers & control circuits are realized on GaAs substrate whereas 1W, 2W amplifiers & high power T/R switch are based on the robust GaN process. Measured results indicate that the T/R module has good VSWR with low RMS amplitude & phase errors over the entire frequency range. Tentative Size of the T/R module developed is 78mm x 19mm x 6 mm (L x W x H).
