NRD NRD Waveguide Transceiver for Millimeter Wave

摘要

PURPOSE: A millimeter wave band transceiver using an NRD guide(non-radiative dielectric waveguide) is provided to prevent a transmitted signal from flowing in a received signal. CONSTITUTION: A millimeter wave band transceiver comprises a transmission end including an antenna(3), an ASK modulator and a transceiving duplexer, and a receiving end including an antenna(3), a balance mixer and a transceiving duplexer. The ASK modulator has a ferrite resonator(7) as a first circulator, and an input port, a breaking port and an output port spaced from each other by 120 around the ferrite resonator(7). The balance mixer has a band part and an NRD guide straight line. The transceiving duplexer has a ferrite resonator(6) as a second circulator, and the antenna(3), a transmitting band pass filter and a receiving band pass filter spaced from each other by 120 around the ferrite resonator(6).
