P/N 70841A-3 Switched Filter Bank


P/N 70841A-3 top viewP/N 70841A-3 Bottom view of Filter

A low frequency switched filter bank with amplification for minimizing insertion loss. It contains 3 Gaussian bandpass filters with a center frequency of 30 MHz and varied bandwidths. Switching is via high speed GaAs switches that permit path selection in less than 100 nanoseconds.
