WebMar 1, 2024 · "The answer to the detector question should be obvious. The backside of a diode die is the cathode which easy to bond to ground and leaves the anode as the negative output. For a positive detector the die must be bonded to an insulator like ceramic to reverse the polarity." KI4NPV 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
