Abstract
A microwave isolator including a driving circuit and a receiving circuit, wherein the driving circuit receives an input signal from a first isolated circuit and generates a corresponding radio frequency (RF) signal and the receiving circuit detects and decodes the corresponding RF signal and provides a corresponding output signal to a second isolated circuit. The driving circuit contains an oscillator for generating the corresponding RF signal based on the input signal from the first isolated circuit, a transmitting antenna for transmitting the corresponding RF signal, and a microwave switch interposed between the oscillation means and the transmitting antenna for switching the RF signal to the antenna. The receiving circuit contains a receiving antenna to receive the corresponding RF signal and means for detecting and decoding the received corresponding RF signal and providing the corresponding output signal to the second isolated circuit.
