Abstract(in English) | Report a good effect of preselector which is useful to reduce numerous interference resulting from collocation of airborne VHF transceivers and their simultaneous operation. Research and experiment for the interference were carried out in order to confirm its mechanism at the field. Unwanted frequency suppression capability at the front end in the receiver portion of the VHF transceiver was measured and studied. As a result of the studies to reduce the interference, a contrivance tuning circuit using high Q varactor diodes application and an exclusive AGC circuit were developed and installed in the preselector. |
