Patent ID: 7260363

Claim:
A universal power amplifier for amplifying and filtering transmit and receive signals, comprising: an input switch for switching the transmit and receive signals wherein the transmit and receive signals are at radio frequencies; a first transmit path connected to the input switch, said first transmit path for filtering and amplifying a first transmit signal, wherein said first transmit path comprises a first agile filter for filtering the first transmit signal; a first receive path connected to the input switch, said first receive path for filtering and amplifying a first receive signal, wherein said first receive path comprises the first agile filter for filtering the first receive signal; a power output stage connected to the first transmit path, said power output stage for amplifying the first transmit signal into a high-power first transmit signal; a transmit/receive matrix switch connected to the power output stage and the first receive path, said transmit/receive matrix switch for switching an antenna between the power output stage and the first receive path; a first transmit/receive switch for switching the first agile filter between the first transmit signal and the first receive signal; a low-noise amplifier connected to the first agile filter and to amplify the first transmit signal; a second agile filter connected to the low-noise amplifier and to filter the first transmit signal; and a second transmit/receive switch connected to the second agile filter and to switch the first transmit signal to the power output stage.
