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.
