Abstract
A surface acoustic wave (SAW) filter that receives an aggregate circuit and outputs two or more sub-signals on outputs each of a different frequency band. The sub-signals are amplified by low noise amplifiers and, in one implementation, the amplified sub-signals can be summed. The outputs are connected via a switched passive network so that portions of the sub-signals on the outputs that are not in the selected frequency band are at least partially terminated.
Claims21
(canceled)
A device to amplify aggregate signals comprising:
- at least one filter configured to receive a signal, and when the received signal is an aggregate signal, to separate the aggregate signal into a plurality of sub-signals having different frequency bands and to output the plurality of sub-signals onto a plurality of outputs;
- a plurality of amplifiers in communication with the plurality of outputs and configured to amplify the plurality of sub-signals;
- and
- a network in communication with the plurality of outputs and configured to switch between a first configuration where the network terminates at least a portion of the signals on the plurality of outputs when the received signal is the aggregate signal and a second configuration where the network is not terminating at least a portion of the signals on the plurality of outputs when the received signal is a non-aggregate signal.

A wireless electronic device comprising:
- an antenna configured to receive and transmit wireless signals;
- at least one filter configured to receive an aggregate signal received by the antenna, to separate the aggregate signal into a plurality of sub-signals having different frequency bands, and to output the plurality of sub-signals onto a plurality of outputs;
- a plurality of amplifiers in communication with the plurality of outputs and configured to amplify the plurality of sub-signals;
- and
- a network in communication with the plurality of outputs and configured to switch between a first configuration where the network is connected to the plurality of outputs when the received signal is the aggregate signal and a second configuration where the network is not connected to the plurality of outputs when the received signal is a non-aggregate signal.

A method to amplify aggregate signals, the method comprising:
- separating a received signal into a plurality of sub-signals having different frequency bands when the received signal is an aggregate signal;
- outputting the plurality of sub-signals onto a plurality of outputs;
- amplifying the plurality of sub-signals;
- when the received signal is the aggregate signal, connecting the plurality of outputs to an impedance network configured to terminate at least a portion of the signals on the plurality of outputs;
- and
- disconnecting the signals on the plurality of outputs from the impedance network when the received signal is a non-aggregate signal.
