Abstract
An intermittently driven transmitter having high power output which is driven intermittently so as to transmit a signal via, for example, a satellite in which the voltage supplied to the transmitter is boosted and supplied to a capacitor. When the signal is to be transmitted, the voltage stored on the capacitor is supplied to a constant voltage circuit which generates a constant voltage which is higher than the voltage supplied to the transmitter and which is supplied to a power amplifier in the final stage of the transmitter and, thus, the intermittent type transmitter with a suitable battery drive system is obtained.
