Combined switch and receive tuner for enhanced LTE-TDD system

A mobile terminal comprising:

• at least one antenna;
• an antenna tuner unit (ATU) comprising;
• a transmit/receive (T/R) switch having a receive (RX) throw communicatively coupled to the at least one antenna;
• a receive only antenna tuner circuit having at least one tuning element integrated with the T/R switch on a die, the receive only antenna tuner circuit being directly coupled to the RX throw of the T/R switch, wherein the at least one tuning element is programmable tuning element;
• and
• a controller adapted to program the at least one tuning element.

A diversity antenna system comprising:

• a diversity receive antenna;
• a transmit and receive (T/R) antenna;
• and
• an antenna tuner unit (ATU) comprising:
• a receive only switch having a receive (RX) throw;
• and
• a receive only antenna tuner circuit having at least one tuning element integrated with the receive only switch on a die, the receive only switch being directly coupled to the RX throw, wherein the receive only antenna tuner circuit is communicatively coupled to the diversity receive antenna through the receive only switch.

A transceiver interface comprising:

• an antenna;
• and
• an antenna tuner unit (ATU) comprising:
• a transmit and receive (T/R) switch having a receive (RX) throw;
• and
• a receive only antenna tuner circuit having at least one tuning element integrated with the T/R switch on a die, the receive only antenna tuner circuit being directly coupled to the RX throw, wherein the receive only antenna tuner circuit is communicatively coupled to the antenna through the T/R switch.
