  • Abstract
    A microstrip variable coupling directional couplers for 4 GHz band have been proposed and tested. By changing the junction capacitances of the varactor diodes, the coupling varies from 4 dB to 20 dB, and the directivity varies from 16 dB to 29 dB. Available frequency range is from 2.7 GHz to 5.3 GHz.
