A high isolation RF switch designed for amorphous flat air-ground ad-hoc network platform

Abstract

Abstract In this paper, a single-pole, double-throw (SPDT) RF switch is designed for the amorphous flat air-ground ad-hoc network platform, which is used to connect the node, low noise power amplifier and power amplifier. The switch controls the transmission and reception of signals in the node according to the variation of excitation voltage. The simulation results show that the RF switch insertion loss is less than 1.5dB, isolation is more than 40dB and the 0.1 dB compression is 38dBm in the frequency band 2.4GHz to 2.5GHz, which can meet the requirements of the ad-hoc network platform. Networking tests results showed that the topology of ad-hoc networks remains stable within a certain distance and the direction of signal in the node is controlled by the switch.
