Microwave Active Network Synthesis
Abstract
The report describes the application of meander lines to impedance transformers, and discusses two types of negative-impedance circuits and two slot-line topics. It is demonstrated that meander lines constitute a class of impedance transformers of which stepped-impedance transformers are a special case. Two types of negative-impedance-converter (NIC) circuits were designed and constructed: (1) a high-power NUNIC, and (2) a FET-NIC filter. A high- power NUNIC circuit intended for operation at 200 to 500 MHz was built and produced negative resistance from below 80 MHz to above 680 MHz. A lossless one-pole filter incorporating the NUNIC was built for operation at 230 MHz and exhibited a 3-dB filter bandwidth of 2.7 MHz.
