Abstract:
1. 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, wherein the PA amplifies signals for transmission with a tunable ferro-electric band pass filter (FE BPF) in response to the 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; and, after the power amplifier is turned off and the LNA is turned on, receiving communications in the adjusted receiving resonant frequency band.
