Microwave Circuit Multiplier

Gregory explains the working principle of a Frequency Multiplier Microwave Circuit, designed to double an input frequency of 2.5 GHz to 5 GHz.

The design uses microstrip techniques, accommodating a high gain microwave transistor amplifier and edge-coupled band-pass filter.

Measurements are made, demonstrating effects in performance when the transistor collector bias current is changed.
