Abstract: An amplifier includes a gain transistor including a control terminal to receive an input signal. A degeneration inductor is coupled between the first terminal of the gain transistor and ground. A shunt inductor and a capacitor are coupled in series between the control terminal of the gain transistor and ground, and form a filter to attenuate frequencies of the input signal within a frequency range. The degeneration inductor and the shunt inductor form a transformer to provide impedance matching.

Abstract: An apparatus is disclosed for processing a signal with a divided amplifier. In example implementations, an apparatus includes a first portion of an amplifier, a first port interface, a second port interface, and a switch matrix. The first port interface includes a first transformer; a second portion of the amplifier, which is coupled to the first transformer; and a first switch component that is coupled to at least one of the first transformer or the second portion of the amplifier. The second port interface includes a second transformer and a second switch component that is coupled to the second transformer. The switch matrix is coupled between the first switch component and the first portion of the amplifier and between the second switch component and the first portion of the amplifier. The switch matrix is also coupled between the second portion of the amplifier and the first portion of the amplifier.
