Flatness of <1dB and phase linearity of <10 degrees within each band were also achieved. Maximum loss within pass bands was less than 17 dB.
A second example is the M-3450, which takes seven RF inputs and provides one coupled output and one filtered output for each input. The RF inputs are 1-2 GHz, 2-4 GHz, 4-8 GHz, 8-12 GHz, 12-18 GHz, 18-26.5 GHz, and 26.5-40 GHz. Each input is followed by a 10 dB, multi-section coupler and a 16 section bandpass filter.
