Crystal detector in microwave
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.
