FM TRANSCEIVER FOR NRD GUIDE HAVING OSCILLATOR REAR FM MODULATOR THEREON

摘要

PURPOSE: An FM transceiver for an NRD guide having an oscillator rear FM modulator thereon is provided to drive an FM modulation on a rear side of an oscillator by constructing a VCO(Voltage Control Oscillator). CONSTITUTION: An oscillator, a modulator and an antenna are installed between an upper conductive plate(1) and a lower conductive plate(2). A Gunn diode is mounted on a Gunn diode mount(6). A modulating part comprises the Gunn diode mount(6), a strip oscillator(7) and a mode suppressor(5). A modulated signal is transmitted to a rod antenna(4) through an NRD guide line(3). A VCO(Voltage Control Oscillator) comprises a rear teflon(12) which has a length of L2. A front teflon(8) has a predetermined air gap on a rear side of the oscillating part and has a length of L1.
