Abstract
A microstrip switch includes N-input switch arms and an output port formed from a microstrip transmission line. Each input switch arm includes one or more p-i-n diodes. The input switch arms as well as the output port are connected at a radially combined center patch. In order to improve the insertion losses at millimeter wave frequencies, the center patch is air suspended in order to reduce the parasitic shunt capacitance in order to extend the low pass frequency response of the switch.
