A radiotelephone (208) for use in a radiotelephone system, the radiotelephone including an oscillator (203) and a buffer amplifier (211) and a transmitter (206). The transmitter (206) is pulsed, causing audio frequency voltage variations in the power supply (207). The radiotelephone (208) generates power and a bias signal for the oscillator (203). The buffer amplifier (211) and the oscillator (203) are in a "stacked" configuration. The buffer amplifier (211) diminishes the audio frequency voltage variations caused by the pulsed transmitter in the power and bias signals generated for the oscillator (203). |
