UWB Pulse Generation Techniques With Switched Resonators

Power efficient UWB pulse generation techniques have been introduced. A simple, compact, and efficient RF pulse compression technique based on a switched resonator concept is used for the pulse generation. It utilizes different charging/discharging speeds of the circuit resonator by varying the resonator´s Q factor and can be applied to any other microwave resonators. The approach compresses the duration of the pulse envelope without changing the phase characteristics of the RF carrier. The paper discusses the basic theory of switched resonators and the methodology of designing then for UWB pulse generation and compression
