Patent ID: 7831213

Claim:
A method of controlling a tower-top low noise amplifier (TTLNA) comprising: configuring a TTLNA to the transmit mode by removing a low noise amplifier (LNA) from a receive signal path, wherein removing the LNA from a receive path includes grounding an input of the LNA and terminating the output of the LNA; at a TTLNA receive duration timing circuit, detecting a start of a radio frequency (RF) transmit signal and an end of an RF transmit signal and responsively generating a receive mode control signal; configuring a TTLNA to the receive mode by placing the LNA into the receive signal path in response to detecting the end of the RF transmit signal; and returning the TTLNA to the transmit mode in response to the receive mode control signal generated at the TTLNA in response to the receive duration timing circuit.
