A compact, quasi-active delay-line limiterfilter QUADLF was designed to limit high-power, fast-rise-time pulses and prevent spike leakage, which is common to conventional limiting techniques. The QUADLF design incorporates both waveguide and microstrip technologies. Over the operating frequency range, from 0.8 to 1.2 GHz, experimental results showed less than 2-dB transmission loss below 10-mW input power and greater than 20-dB in-band isolation above 5.0-W input power. Design procedures are outlined and experimental data are presented that demonstrate feasibility and applicability. Data on frequency response, temporal response, and isolation characteristics are also shown.
