Single signal transmit/receive module amplifier switching control

摘要

A method for single signal transmit/receive module amplifier switching control is disclosed. Step (A) of the method may receive a control signal through a single pin of a circuit. The control signal may alternately conveys (i) a receive mode and (ii) a transmit mode. Step (B) may generate a transmit signal in a disabled state in response to the control signal transitioning from the transmit mode to the receive mode. The transmit signal in the disabled state is generally configured to disable a transmit amplifier. Step (C) may generate a receive signal in an enabled state a receive delay time after the control signal transitions from the transmit mode to the receive mode. The receive signal in the enabled state is generally configured to enable a receive amplifier. The receive delay time may allow the transmit amplifier to switch off before the receive amplifier switches on.

1. A method for single signal transmit/receive module amplifier switching control, comprising the steps of:
(A) receiving a control signal through a single pin of a circuit, wherein said control signal alternately conveys (i) a receive mode and (ii) a transmit mode; (B) generating a transmit signal in a disabled state in response to said control signal transitioning from said transmit mode to said receive mode, wherein said transmit signal in said disabled state is configured to disable a transmit amplifier; and (C) generating a receive signal in an enabled state a receive delay time after said control signal transitions from said transmit mode to said receive mode, wherein (i) said receive signal in said enabled state is configured to enable a receive amplifier, and (ii) said receive delay time allows said transmit amplifier to switch off before said receive amplifier switches on.
