Notes:
1.
The frequency fC is defined as the midpoint between the 3dB
frequencies.
2.
Unless noted otherwise, all measurements are made with the filter
installed in the specified test fixture that is connected to a 50Ω test
system with VSWR ≤ 1.2:1. The test fixture L and C are adjusted
for minimum insertion loss at the filter center frequency, fC. Note
that insertion loss, bandwidth, and passband shape are dependent
on the impedance matching component values and quality.
3.
Unless noted otherwise, specifications apply over the entire
specified operating temperature range.
