Patent ID: 7415246

Claim:
A method for determining attenuation of a transmit/receive switch for attenuating inbound radio frequency signals, the method comprises: enabling the transmit/receive switch to provide a loop back configuration between a transmit section and a receive section; providing, by the transmit section, a test radio frequency signal to the receive section; measuring, by the receive section, signal strength of the test radio frequency signal to produce a first signal strength; enabling receive attenuation mode of the transmit/receive switch; providing, by the transmit section, the test radio frequency signal to the receive section via the transmit/receive switch in the receive attenuation mode to produce an attenuated test radio frequency signal; measuring, by the receive section, signal strength of the attenuated test radio frequency signal to produce a second signal strength; and comparing the first signal strength with the second signal strength to determine attenuation of the transmit/receive switch.
