In this rf switch, the PIN diodes are used to shut on of off several antennas. The current source is a 12 volt circuit composed of a transformer, bridge rectifier and a regulator IC. In order to know ...

diodes, and integrated circuits (ICs), allowing engineers and technicians to understand how electronic circuits are designed and built. Single pole, single throw switch (SPST) photo and diagram ...

Figure 2 The simple addition of a bypass diode makes this timer circuit valid for low duty cycles. Diode forward voltage depends on the current flowing through the diode. This current can range from a ...
