Notes:
1.
The frequency
f
C
is defined as the midpoint between the 3dB
frequencies.
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,
f
C
. Note
that insertion loss, bandwidth, and passband shape are dependent
on the impedance matching component values and quality.
Unless noted otherwise, specifications apply over the entire
specified operating temperature range.
