Excluding losses due to matching Including losses in matching test circuit shown below
Amplitude Ripple - 960 MHz Absolute Attenuation - 880 MHz - 905 MHz - 915 MHz - 1050 MHz - 6000 MHz Input VSWR - 960 MHz Output VSWR - 960 MHz Output Phase Balance - 960 MHz Output Amplitude Balance - 960 MHz Optimal Source Impedance (4) Optimal Load Impedance (4) Notes:
All specifications are based on the test circuit shown below This specification is valid for room temperature only. The specification over the full temperature range(s) is available on the next page(s) Electrical margin has been built into the design to account for the variations due to manufacturing tolerances This is the complex conjugate of the unmatched filter's impedance resulting in maximum power transfer
