RF SP4T PIN Diode Switch for Mobile Satellite Communication System at Ku-band
This paper presents the development of a switching circuit as a part of the design of a mobile transceiver in the Ku-band. It is used as a section of the radiating system with Rotman lenses and an antenna array. The microwave switch is designed with PIN diodes in a parallel architecture due to the necessity for low insertion loss, high insulation, low return loss, and possibly a high incident power. The microstrip circuit was developed and simulated showing good theoretical results and reliability to the deviation of a manufacturing process.
