MICROWAVE REFLECTION AMPLIFIERS HAVING INCREASED BANDWIDTH

Abstract

A four diode reflection amplifier having a relatively wide bandwidth of at least 5 percent over the frequency range of 43.5 to 45.5 GHz includes three magic Ts arranged to provide a 4-way passive power combiner. The 4-way passive power combiner symmetrically couples each of the four diode amplifiers to an input/output port of the reflection amplifier. To provide the improved bandwidth performance, a perturbation impedance in the form of a single shunt capacitance is inserted at the input/output port of the reflection amplifier to provide a selected perturbation in the load impedance and hence the reflection characteristic seen by the reflection amplifier over a selected band of operation of the amplifier.
