Webtype of crystal video receiver. A 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 circuit can be combined. If WebCrystal (Xtal) detectors are semiconductor devices that are used extensively to rectify microwave signals so that their amplitudes and modulations can be monitored on …
