RF Switch - BJT transistor as switch
Can a BJT transistor be used as an RF switch?
In this video we are going to take a look at the usage of a BJT transistor as a Diode RF Switch. The base-emitter and base-collector junctions are used in the place of diodes in a standard RF switch topology.
The isolation and insertion loss of the device is measured and characterized.
