Abstract

A dual‐band RF switch that utilizes composite right/left handed (CRLH) transmissions‐lines(TLs) and PIN diodes is proposed. The design method of RF switch is based on the phase characteristic of the CRLH‐TL, which can be adjusted arbitrary, and employed conventional type‐II; filter structure. The use of multiple PIN diodes as switching element offers prominent performance such as low insertion loss, low power consumption, and high isolation. Theoretical performance of RF switch is verified through the circuit simulations and the measurement of a fabricated prototype at 0.8 GHz and 1.6 GHz. © 2008 Wiley Periodicals, Inc.
