Abstract
Disclosed herein is a dual band high frequency amplifier using a composite right/left handed (CRLH) transmission line (TL). Accordingly, a CRLH TL structure having a dual band characteristic is inserted into an input matching circuit and/or an output matching circuit in the high frequency amplifier, and a matching circuit is designed so that impedance matching is performed at two frequencies, thereby obtaining both gain and matching characteristics at the two frequencies.
