WebApr 1, 2000 · A detector at the end of the tube gives an output proportional to the number of cesium atoms striking it, and therefore peaks in output when the microwave frequency is exactly correct. This peak is then used to make the slight correction necessary to bring the crystal oscillator and hence the microwave field exactly on frequency. WebA crystal receiver can be broken down into four basic parts: an antenna, a tuned circuit, the detector, and an amplifier (see Fig. 1 ). The most common tuned circuit is not really a tuned circuit but a high-pass filter, a waveguide. In this mode, the antenna and tuned cir- cuit can be combined. If the detector is mounted in carbon centered radicalWebThe microwave source and the crystal detector are normally contained within one unit known as the microwave bridge. The microwaves are introduced into the sample cavity via a waveguide and the reflected radiation returns to the microwave bridge.
