Abstract
The present invention discloses a straight-through-repeater which relays a frequency-modulated microwave signal. The straight-through-repeater is basically comprised of a phase-locked loop circuit located between receiving and transmitting antennas of the repeater. The phase-locked loop circuit has a demodulating capability for reproducing a baseband signal, a power amplifying capability, a very narrow filtering capability, an automatic gain controlling capability and an amplitude limiting capability. The repeater is further comprised of a means for suppressing a step-out of synchronism occurring in the phase-locked loop circuit.
