Abstract

PURPOSE:To prevent the transient oscillation produced at the application of power supply of an FM transmitter and its duration, by applying a power application to amplifying circuits at the poststage, after the prestage of an active circuit reaches a steady state. CONSTITUTION:When a switch 9 of a power supply 10 of an FM transmitter is applied, a quartz oscillating circuit 1 is oscillated. Next, this oscillation signla is amplified at an amplification circuit 2, multiplied at a multiplification circuit 3, and further amplified at amplifier circuits 4, 5. On the other hand, the power supply for an excitation amplifying circuit 6 and a power amplifier 7 of the poststage is applied with a timer 11 after about twice the leading time of oscillation of a crystal oscillation circuit 1 from the application of power supply to the circuits 1-5 of the prestage.
