Abstract
In order to implement novel utilization methods, implementation of a low power consumption and high sensitivity RF receiving system is desired. A microwave frequency band stub resonance booster circuit characterized by boosting the amplitude of an RF signal in a passive operation by resonating in series a 0.2 pF to 0.01 pF micro-capacitor element with a λg/2 open stub element to perform impedance conversion of the input RF signal is used. In addition, since a capacitor which has been conventionally inserted in order to repeat charging and discharging of the RF signal by using two diodes becomes useless by putting a DC resonant component of resonant-boosted output into an open state when voltage-doubling and rectifying the resonant-boosted RF signal, rectified output can be obtained and high-sensitivity reception and detection of the RF signal becomes possible without being affected by the capacitor which imparts comparatively large insertion loss.
