LEAD FREE MAAMSS0041 V1 Broadband CATV Amplifier 50 - 1000 MHz Enhanced Input Return Loss (IRL) and Gain Flatness An enhanced input return loss and improved gain flatness circuit has been developed for applications where those parameters are key to system performance. Adding a series inductor, L3, to the input, a shunt capacitor, C5, to the output, and changing the bias inductor, L1, value will improve the input return loss to 25 dB typical from 50 to 1000 MHz. The gain flatness will also improve to less than 0.3 dB from 50 to 1000 MHz.
