Abstract :
A high efficiency harmonic re-radiator, consisting of a diode doubler and conjugate-matched receive and transmit antennas, is described. The device operates by receiving a 1.3 GHz signal and re-radiating a 2.6 GHz signal. The doubler design is optimized for low input power operation and provides 1% conversion efficiency at -30 dBm input. It is shown that utilizing proper harmonic terminations in the computer simulations is critical for accurate performance prediction.
