System and method for filtering time division multiple access telephone communications

A method for transceiving Time Division Multiple Access (TDMA) telephone communications through a common filter, the method comprising:

• selectively filtering to produce transmitter frequency passbands and receiver frequency passbands, different than the receiver frequency passbands;
• at a first time, transmitting filtered communications in the transmitter frequency passband, when a power amplifier (PA) is on and an LNA is off, wherein the PA amplifies signals for transmission in a tunable, ferro-electric band pass filter (FE BPF) in response to the PA being on;
• and,
• at a second time, different than the first time, receiving communications in the receiver frequency passband, when the power amplifier (PA) is off and the LNA is on.

A method for transceiving Time Division Multiple Access (TDMA) telephone communications through a common filter in a wireless communications device, the method comprising:

• adjusting a transmitting resonant frequency in response to a tuning voltage signal;
• turning on a power amplifier (PA) in response to a power amplifier (PA) activation signal;
• turning off a low noise amplifier (LNA) in response to a LNA deactivation signal;
• after the power amplifier is turned on and the LNA is turned off, transmitting transmission communications in the adjusted transmitting resonant frequency band;
• turning off the power amplifier in response to a power amplifier deactivation signal;
• adjusting a receiving resonant frequency, different from the transmitting resonant frequency, in response to the tuning voltage signal;
• turning on the low noise amplifier (LNA) in response to a LNA activation signal, wherein the LNA amplifies communications supplied by a tunable, ferro-electric band pass filter (FE BPF) in response to the LNA activation signal;
• and,
• after the power amplifier is turned off and the LNA is turned on, receiving communications in the adjusted receiving resonant frequency band.
