This article presents two MEMS‐based single‐pole double‐throw (SPDT) circuit designs using Raytheon's capacitive switch technology. One uses a series‐shunt topology for broadband operation covering 5–24 GHz with less than 1‐dB insertion loss and 25‐dB isolation. The second design employs resonant quarter‐wave sections to achieve loss below 1 dB across 24–31 GHz. © 2004 Wiley Periodicals, Inc. Int J RF and Microwave CAE 14: 383–387, 2004.
