Abstract :
A high-performance GaAs SP3T switch has been developed using asymmetrical design of the transmit and receive paths. A combination of stacked FETs and multi-gate PHEMT FETs with high breakdown voltages and large peripheries was implemented in this design. Insertion loss of less than 0.8 dB and isolation greater than 25 dB to 2 GHz were obtained. With a positive 3-V control voltage, power handling of the device exceeded 34 dBm while maintaining second and third harmonic levels better than 65 dBc.
