Abstract
An apparatus, including: a receiver including a low noise amplifier (LNA) configured to amplify a received radio frequency (RF) signal based on a first protocol; a transmitter configured to generate a transmit RF signal based on a second protocol; and a first control circuit configured to control a gain of the LNA based on information regarding the transmit RF signal and the received RF signal.
Claims29
An apparatus, comprising:
- a receiver including a low noise amplifier (LNA) configured to amplify a received radio frequency (RF) signal based on a first protocol;
- a transmitter configured to generate a transmit RF signal based on a second protocol;
- and
- a first control circuit configured to control a gain of the LNA based on information regarding the transmit RF signal and the received RF signal;
- wherein the receiver comprises:
- one or more frequency downconverting stages configured to generate a received baseband signal based on the received RF signal amplified by the LNA;
- and
- a second control circuit configured to control the gain of the LNA based on an energy estimation of the received baseband signal.
