Abstract :
A switch for millimeter wave applications is introduced. It uses two air-gap switched capacitors, to load a transmission line in order to control the insertion and the return losses. To improve the bandwidth behavior the two air-gap switched capacitors are put at two different points along the transmission line. The whole structure is fabricated on quartz using an in-house MEMS technology. Based on the simulation results, the structure shows a switching behavior from 52GHz to 62GHz. The simulated insertion and return losses of the switch for the up state are better than 1.6dB and 10dB respectively. On the other hand, the switch shows an isolation of better than 15dB for the aforementioned bandwidth.
