A GaAs MMIC chip set for 2 to 5 GHz fixed wireless services delivery

The emergence of volume markets for fixed wireless delivery of telephony and data in the 2 to 5 GHz band drive the design of low cost integrated radio transceivers. The design of three GaAs MMICs for the implementation of a 3.5 GHz radio front-end is described, which together with catalogue available silicon integrated circuits forms the radio part of a residential transceiver for fixed wireless service delivery. The three low cost plastic packaged GaAs chips constitute a receive down-converter, transmit up-converter and +31.6 dBm power amplifier. The application of this GaAs chip set to broadband (data) wireless access is also considered.
