Abstract
The authors shown how an active antenna transmitter module can haw its freq uency stability improved using FM demodulation techniques. A closed loop fe edback strategy is presented, in order to improve the bias pushing characte ristic of the active antenna from 41MHz/V to 5MHz/V. A linearised feedback model for the system is also presented which predicts the frequency pushing characteristic to be 7 MHz/V.
