Low cost 60 GHz RF front end transceiver integrated on organic substrate

This paper presents, for the first time, a low cost, 60 GHz, RF front-end Tx/Rx integrated with a Yagi-Uda antenna array on organic Liquid Crystal Polymer substrate. The Tx/Rx module consists of a GaAs LNA, PA and a Single Pole Double Throw (SPDT) switch wirebonded on a single, multilayer substrate. The array was designed for operation at 60.6 GHz with a gain of 12.1 dBi. The radiation pattern measurements were conducted and showed an active antenna gain of 31.8 dB for the receiver and 21.6 dB of gain for the transmitter. It demonstrates 19.7 dB and 9.5 dB of added gain from the integrated receive and transmit modules respectively. The array has 1 and 3 dB deviation in gain in receiver and transmitter modules respectively from 55-63 GHz.
