Abstract:
An RF circuit system comprises a processing unit for generating an RF signal, a first antenna for transmitting the RF signal, a transmitting suppressor including serially connected filters between the first antenna and the processing unit for filtering the RF signal to generate multiple different suppressed RF signals, a second antenna for receiving the RF signal, and an isolation detector for measuring an isolation value representing isolation between the first and second antennae with respect to the RF signal. The transmitting suppressor outputs the RF signal when the isolation value is not smaller than a threshold, and outputs one suppressed RF signal with reference to the difference between the isolation value and the threshold when otherwise.
