Abstract: A flexible, reconfigurable, power efficient transmitter device and method is provided. In one embodiment, the method includes receiving outbound data and determining a mode of operation. When operating in a first mode the method may include modulation mapping the outbound data according a modulation scheme to provide first modulation mapped digital data, converting the first modulation mapped digital data to an analog signal that comprises an intermediate frequency (IF) analog signal, upconverting the IF analog signal to produce a first modulated radio frequency (RF) signal based on a local oscillator signal, amplifying the first RF modulated signal to produce a first RF output signal, and outputting the first RF output signal via an isolator.

Abstract: A continuously tunable linear phase filter having a ground connection includes a three-terminal Bessel filter having an input terminal for receiving a signal, an output terminal for delivering a signal, a control terminal for receiving a control voltage, and a varactor. Each of the terminals are in signal communication with each other and the varactor is in signal communication with each of the terminals and ground, the varactor being responsive to the control voltage at the control terminal. The capacitance of the varactor is continuously adjustable in response to a change in the control voltage at the control terminal, thereby enabling continuous tuning of the continuously tunable linear phase filter in response to the control voltage.
