Abstract

The invention provides circuitry integrated into a silicon chip that measures aspects of an RF signal on a transmission line in order to provide data that is ultimately used by an antenna tuner circuit to substantially match the impedance of the antenna with that of the transmission line providing the RF frequency to be transmitted.

Description

technical field [0001] The present invention relates to standing wave ratio (SWR) meters and associated circuitry that may be adapted for incorporation into integrated circuits. In particular, embodiments of the invention relate to transmission circuitry in a mobile device, base station, or other RF transmission device, wherein the transmission circuitry includes standing wave ratio measurement circuitry adapted to provide data or information that can be used to adjust The impedance seen by the transmission antenna is used to improve the impedance match of the antenna to the RF transmission line and thereby help maximize the power output of the RF transmission circuit for various transmission RF frequency channels. Background technique [0002] Typically, the performance of cellular antennas is far from ideal. A significant portion of the transmitter power output is usually reflected back from the antenna due to poor antenna impedance matching. When a single transmit frequ...
