Classification: CPC H | IPC H

Claim 10:
11. A method of signal processing in a mobile device, the method comprising:
in a first mode, transmitting an ultra-high band transmit signal from a high-band power amplifier along a signal path configured to support both ultra-high band and high band signals to a multi pole multi throw switch, and passing the ultra-high band transmit signal through an ultra-high band filter to an antenna configured to support ultra-high band and high band signals;
in a second mode, transmitting a high-band transmit signal from the high band power amplifier along the signal path configured to support both ultra-high band and high band signals, and tuning the ultra-high band filter such that the high-band transmit signal reaches the antenna configured to support ultra-high band and high band signals; and
in a third mode, transmitting an ultra-high band receive signal from the antenna through the ultra-high band filter, routing the ultra-high band receive signal through the switch to an ultra-high band signal path configured to support ultra-high band receive signals, transmitting a high-band receive signal from the antenna through a high-band filter, the high band filter being diplexed with the ultra-high band filter and being connected to a signal path configured to support high-band receive signals.
