Solid State RF/Microwave Switch Technology: Part 2

  • Author: Rick Cory and Dave Fryklund
In part 1 we discussed an overview of RF/microwave switch topologies, PIN diode theory of operation, and some simple PIN diode switch implementations. In part 2 we will discuss more complex PIN diode switches, the theory of operation of RF/microwave field effect transistors (FETs) -- with emphasis on the pseudomorphic high electron mobility transistor (pHEMT) -- and its implementation in RF/microwave switches. We will also describe criteria with which the relative advantages of PIN diode switches and pHEMT switches compare for specific types of applications.
