MEMS switch for cell-phone RF (radio-frequency) front-ends. The MEMS effort at RFMD includes electrical engineers, physicists, and chemical engineers. "MEMS can be an interesting place to work because it is multidisciplinary, " says Hammond. "You are actuating a machine with currents and voltages, so...

The simplest solid-state RF switch employs a PIN diode as a switching element. PIN diodes are named for a region of undoped intrinsic semiconductor lying between their p and n-type material. This area eliminates capacitance effects between the n and p-type areas that can otherwise lower device...
