Delay modules consisting of surface acoustic wave SAW delay lines, equalizers, and amplifiers have been implemented. Ultra-flat or - 0.1 dB passband frequency response over a 215 MHz bandwidth centered at 800 MHz has been demonstrated for 7.5 microsec of time delay. Module gain of up to 10 dB was achieved. Cascading three modules and using a feedback loop to simulate additional cascade elements demonstrated 500 microsec of time delay over 200 MHz bandwidth in a linear system. Author
