Abstract:
A system and method are presented for transceiving Time Division Multiple Access (TDMA) telephone communications through a common filter. The system includes a tunable ferro-electric bandpass filter (FE BPF), a controller, a low noise amplifier (LNA), and a power amplifier (PA). The FE BPF has a control input to accept tuning voltage signals from the controller and two signal ports. In response to the tuning voltage signals, the FE BPF selects a transmit or receive frequency passband between the signal ports. The FE BPF first signal port is connected to the LNA and the PA and the FE BPF second signal port is connected to an antenna in a wireless device. The LNA and PA are activated and deactivated in response to control signals from the controller.
