Abstract
A differential amplifier is disclosed with harmonic terminations. The differential amplifier has a first transistor having a first emitter coupled to a fixed voltage node, a first base, and a first collector. A second transistor has a second emitter coupled to the fixed voltage node, a second base, and a second collector. A first capacitor and a first inductor are coupled in series between the first collector and a virtual ground node. A second inductor and a second capacitor are coupled in series between the second collector and the virtual ground node, and a third inductor is coupled between the virtual ground node and the fixed voltage node. The first and second capacitors and first, second, and third inductors have capacitances and inductances, respectively, that are sized to realize second and third harmonic traps for a radio frequency signal being amplified by the differential amplifier.
