Title
(EN) RADIO FREQUENCY TRANSMITTER HAVING SWITCHED MODE POWER SUPPLY
(FR) EMETTEUR A HAUTES FREQUENCES A ALIMENTATION EN COURANT EN MODE COMMUTE
Abstract
(EN)
A hand-held radio frequency transmitter (10) for use in generating a coded radio frequency transmission has a switched mode power supply (12) energizable by a battery (52). A radio frequency oscillator (14) is driven by the switched mode supply. A modulator (146) controls operation of the oscillator which produces a coded radio frequency signal.
(FR)
Emetteur (10) à hautes fréquences portatif destiné à générer une haute fréquence codée et possédant une alimentation (12) en courant en mode commuté pouvant être excitée par une batterie (52). Un oscillateur (14) à hautes fréquences est excité par l'alimentation en mode commuté. Un modulateur (146) commande le fonctionnement de l'oscillateur qui génère un signal haute fréquence codé.
