Abstract
A method, for transmit signal leakage mitigation in an apparatus includes: determining an antenna reflection parameter corresponding to a transmit antenna of the apparatus based on a first portion of a transmit signal and a reflected signal that corresponds to a reflection of a second portion of the transmit signal by the transmit antenna; and implementing, based on the antenna reflection parameter, a selected signal suppression circuit reflection parameter value of a plurality of possible signal suppression circuit reflection parameter values.

A method, for transmit signal leakage mitigation in an apparatus, comprising:
- determining an antenna reflection parameter corresponding to a transmit antenna of the apparatus based on a first portion of a transmit signal and a reflected signal that corresponds to a reflection of a second portion of the transmit signal by the transmit antenna;
- and
- implementing, based on the antenna reflection parameter, a selected signal suppression circuit reflection parameter value of a plurality of possible signal suppression circuit reflection parameter values.
An apparatus comprising:
- a power amplifier;
- a transmit antenna;
- a memory;
- a signal suppression circuit having a plurality of possible signal suppression circuit reflection parameter values;
- routing circuitry, communicatively coupled to the power amplifier, the transmit antenna, and the signal suppression circuit;
- and
- a processor, communicatively coupled to the memory, the signal suppression circuit, and the routing circuitry, configured to:
- determine an antenna reflection parameter based on a first portion of a transmit signal from the power amplifier and a reflected signal that corresponds to a reflection, by the transmit antenna, of a second portion of the transmit signal from the power amplifier;
- and
- control, based on the antenna reflection parameter, the signal suppression circuit to implement a selected signal suppression circuit reflection parameter value of the plurality of possible signal suppression circuit reflection parameter values.
An apparatus comprising:
- a signal source;
- a power amplifier communicatively coupled to the signal source;
- a transmit antenna;
- transmit routing circuitry communicatively coupled to the power amplifier and the transmit antenna, and configured to selectively couple the power amplifier to the transmit antenna;
- a processor;
- and
- a signal suppression circuit communicatively coupled to the processor and comprising a plurality of reactive components at least one of which has a variable reactance selectable by the processor.
