Abstract :
In this paper, a novel time division duplex (TDD) mode direct digital conversion transceiver using six-port technology is proposed for a QPSK communication. We only use one six-port junction (SPJ) for Tx/Rx mode. To change Tx/Rx mode, we propose a new component, which consists of switched reflection coefficient generator and power detector (SRG&PD). The prototype of the propose six-port transceiver is used to realize the QPSK communication with a 2.4 GHz carrier frequency and 10 Mbps data rates. Also, the proposed transceiver may be used to low cost, low power consumption and reconfigurable RF systems.
