Abstract: EL PUENTE DE CUATRO DIODOS ESTA SITUADO EN POSICION DENTRO DE LA CAVIDAD DE UN OSCILADOR DE DIODO DE GUNN. AL PUENTE DE DIODOS SE APLICA UNA SEÑAL DE SUBARMONICO, Y EL PUENTE DE DIODOS ACOPLA A LA CAVIDAD UN ARMONICO IMPAR DE LA SEÑAL INYECTADA. ASI SE HACE QUE LA CAVIDAD RESUENE AL ARMONICO IMPAR DE LA SEÑAL INYECTADA. LA SEÑAL INYECTADA PUEDE CAMBIARSE USANDO UN SINTETIZADOR DE FRECUENCIAS A FIN DE OBTENER UN OSCILADOR DE MICROONDAS CON FUNCIONAMIENTO EN CANALES MULTIPLES (MULTICANAL). EL PUENTE DE DIODOS PROPORCIONA UNA SEÑAL DE RETROACCION INDICATIVA DE LA FASE DE LA OSCILACION DE LA CAVIDAD. LA SEÑAL DE RETROACCION SE APLICA A UN VARACTOR (REACTANCIA VARIABLE) QUE PRESINTONIZA EL OSCILADOR DE DIODO DE GUNN Y CON ELLO PROPORCIONA UN CONTROL DE FASE SINCRONIZADA.

Abstract: A four-diode bridge is positioned within the cavity of a Gunn diode oscillator. A subharmonic signal is applied to the diode bridge and the diode bridge couples an odd harmonic of the injected signal into the cavity. The cavity is thus caused to resonate at the odd harmonic of the injected signal. The injected signal can be changed using a frequency synthesizer in order to provide a microwave oscillator with multiple-channel operation. The diode bridge provides a feedback signal indicative of the phase of cavity oscillation. The feedback signal is applied to a varactor which pretunes the Gunn diode oscillator and thereby provides phase-locked control.
