POWER SAVING CIRCUITS FOR TIME DIVISION MULTIPLE ACCESS AMPLIFIERS
First Claim
1. A network amplifier, comprising:
- a first communication device for receiving a first Time Division Multiple Access (TDMA) signal, the first TDMA signal including broadcasting timeslots and non-broadcasting timeslots;
a power amplifier for amplifying the first TDMA signal to generate an amplified first TDMA signal;
a sensing circuit for detecting the broadcasting timeslots of the first TDMA signal and for turning the power amplifier on during the broadcasting timeslots and off during the non-broadcasting timeslots so that the power amplifier only amplifies the first TDMA signal during the broadcasting timeslots and does not amplify the first TDMA signal during the non-broadcasting timeslots; and
a second communication device for transmitting the first TDMA signal as amplified by the power amplifier.

Abstract
A method and system for conserving power consumption within a network amplifier. The system includes a first communication device for receiving a Time Division Multiple Access (TDMA) signal. The TDMA signal includes both broadcasting timeslots and non-broadcasting timeslots. A power amplifier amplifies the TDMA signal to generate an amplified TDMA signal. The TDMA signal is analyzed by a sensing circuit for detecting the presence of the broadcasting timeslots. The sensing circuit turns the power amplifier on during the broadcasting timeslots and off during the non-broadcasting timeslots so that the power amplifier only amplifies the TDMA signal during the broadcasting timeslots and does not amplify the TDMA signal during the non-broadcasting timeslots. The resultant amplified TDMA signal is then transmitted by a second communication device.
