Switchless band separation for transceivers

A system comprising:

• a power amplifier to amplify signals of multiple transmission frequency bands;
• a transmit antenna to transmit the amplified signals;
• a plurality of transmit matching networks coupled to the power amplifier;
• a plurality of transmit Band Pass Filters (BPFs) coupled between the transmit matching network and the transmit antenna, wherein the transmit matching network provides multiple impedances tuned to increase impedance to signals outside the transmission frequency bands;
• a receive antenna to receive signals in receive frequency bands;
• a low noise amplifier to amplify signals from the receive antenna;
• a plurality of receive BPFs coupled between the receive matching network and the receive antenna, wherein the receive matching network provides multiple impedances tuned to increase impedance to signals outside the receive frequency bands;
• and
• a receive matching network coupled to the low noise amplifier and the plurality of receive BPFs.

A method comprising:

• receiving signals to be transmitted or amplified along a signal path;
• filtering the signals on the signal path with multiple band pass filters;
• and
• conducting the signals on the signal path through an impedance tuning network;
• tuning an impedance of the impedance tuning network, comprising:
• increasing an impedance for the routing paths other than the pass band path for signals at the pass band frequencies having at least one of the multiple band pass filters;
• and
• matching an impedance for the pass band path for signals at pass band frequencies having at least one of the multiple band pass filters.
