Abstract
An integrated circuit includes an on-chip antenna interface, coupled to an off-chip antenna interface having at least one off-chip impedance matching component, that forms a programmable impedance matching network with the at least one off-chip impedance matching component. The programmable impedance matching network is programmable based on a control signal. An RF receiver, coupled to the programmable impedance matching network, that generates inbound data in response to a received signal from the programmable impedance matching network.

A (radio frequency) RF reception system comprising:
- an off-chip antenna interface that includes:
- a filter coupleable to an antenna;
- at least one off-chip impedance matching component coupled to the bandpass filter;
- an integrated circuit that includes:
- an on-chip antenna interface, coupled to the off-chip antenna interface, that forms a programmable impedance matching network with the at least one off-chip impedance matching component, wherein the programmable impedance matching network is programmable based on a control signal;
- and
- an RF receiver, coupled to the programmable impedance matching network, that generates inbound data in response to a received signal from the programmable impedance matching network.
A method comprising:
- generating, via a control module of an integrated circuit, a frequency selection signal;
- adjusting via the control module of the integrated circuit, a programmable impedance matching network coupled to an antenna, the frequency selection signal and a bandpass filter, the programmable impedance matching network formed by at least one off-chip impedance matching component and an on-chip adjustable impedance, by adjusting the on-chip adjustable impedance to a first value based on the frequency selection signal.
