A transceiver and transmitter are shown. A baseband processor receives a signal for transmission. It converts the signal into amplitude and phase polar components. Each component is then processed—the phase component through a wideband phase modulator and the amplitude component through a wideband amplitude modulator, and the components are then recombined for further processing or transmission.

The invention relates to for processing an electromagnetic input signal, wherein the signal is passed through an input to be modified across a plurality of modifying segments using a characteristic of the signal, and wherein the plurality of segments have a plurality of states controlled by a control signal, by determining a reference impedance for the input for one or more states of the plurality of segments; and adaptively adjusting impedance of the input toward the reference impedance. This may be accomplished for example, by using a matching circuit comprising one or more selected from the group consisting of a digital signal processor, a microprocessor, a logic circuit, an integrated circuit, a phase shifter, a resistor, a variable inductor, and a variable capacitor. The matching circuit determines shifts in impedance of the input after a change in state of the segments; and adaptively adjusts the impedance based upon the shift.

A system and method for modulating a phase component of an electromagnetic signal includes a phase/frequency detector having first and second inputs and an output. The first phase/frequency detector input may be configured to receive a reference signal. The system may include an oscillator having an input and an output. The oscillator may be configured to generate a desired oscillator output signal at its output. A divider may be configured to receive the oscillator output signal. The divider may have a divider count input and a divider carryout output that may be connected to the second phase/frequency detector input. A loop filter may be connected in series between the phase/frequency detector output and the oscillator input. The loop filter has a transfer function including at least two frequency response rate change points, where each of the frequency rate change points corresponds to a pole or a zero in the transfer function.

A transmitter comprises a baseband processor, a wideband phase modulator and an amplitude modulated amplifier. A signal is provided through the baseband processor and is converted into polar coordinates, comprised of amplitude and phase components, with the amplitude component being transmitted to the amplitude modulated amplifier. The amplitude modulated amplifier being comprised of independently controllable current sources, and with the phase component being transmitted to the wideband phase modulator, for modulation upon a carrier wave, and subsequent transmission to the amplitude modulated amplifier for amplification according to control imposed by the amplitude component upon the current sources.

A receiver having a circuit configurable to function as a low-noise amplifier or a calibration source and having at least one circuit element that is shared between these two circuit functions. Advantageously, the shared circuit element saves at least the amount of die area that would have been taken by a second instance of that circuit element.
