Abstract :
A new linear tapered diplexing power distributed amplifier (DA) based on composite right left handed transmission line (CRLH-TL) has been proposed and implemented. According to the input frequency, the amplified signal is directed to one of the two output ports automatically. The linearity requirement of UMTS and WLAN can be satisfied until different power level, respectively. Furthermore, this circuit is capable of simultaneous amplification of 2 modulated signals, which enables load balancing and spectrum aggregation techniques.
