Abstract:
1. A receiver, comprising: an antenna for receiving a wireless signal; a single pole single through switch which passes a signal received via said antenna and outputs the signal when a first control signal is in a first state, and connects a signal received via said antenna to a reference potential when the first control signal is in a second state; and a difference circuit which outputs a difference signal of an output signal of said single pole single through switch when the first control signal is in the first state and an output signal of said single pole single through switch when the first control signal is in the second state, wherein when the first control signal is the first state, the single pole single through switch connects the antenna to the difference circuit, and when the first control signal is in the second state, the singe pole single through switch connects the antenna and the difference circuit to the reference potential, and outputs the reference potential.
