| Abstract: | This paper presents a microstrip switch using pin diodes for Ku-band applications.At high frequency,especially for millimeter-wave applications,it is hard to obtain a switch with high-isolation,so this paper makes an effort to develop isolation of the switch using a novel topology that contains multiple unit cells and optimizes parameters of the unit cell circuit.The isolation of the fabricated switch is better than 95dB from 15.75 to 16.25GHz,the insertion loss is less than 4dB,S11 is better than-12dB,S22 ... |
