Abstract :
A microwave transponder is described which is suitable for short-range telemetry applications requiring an inexpensive transmitter. Two antiparallel beam-lead diodes at the terminals of a bow-tie antenna produce double-sideband suppressed-carrier modulation centred about the second harmonic of an externally supplied fundamental carrier. A simple theory predicting performance of the device is confirmed by experiment.
