Method and system for a single-chip fm tuning system for transmit and receive antennas

Abstract

Aspects of a method and system for a single-chip FM tuning system for transmit and receive antennas may include in a frequency-modulation (FM) radio system comprising an integrated FM radio transmitter and FM radio receiver: receiving via a receive antenna for the FM radio system a radio-frequency (RF) signal transmitted from a transmit antenna of the radio transmitter. A frequency response of said receive antenna and/or a frequency response of said transmit antenna may be adjusted based on said received RF signal. The frequency response of the receive antenna and/or the transmit antenna may be adjusted dynamically, autonomously, sequentially and/or simultaneously. The receive antenna and/or the transmit antenna may be adjusted via a programmable filter, which may comprise inductive and capacitive components. The programmable filter may comprise a programmable array of inductors and/or a programmable array of capacitors.
