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.
Frequency aging is the change in
f
C
with time and is specified at
+65°C or less. Aging may exceed the specification for prolonged
temperatures above +65°C. Typically, aging is greatest the first
year after manufacture, decreasing in subsequent years.
5.
Turnover temperature,
T
0
, is the temperature of maximum (or
turnover) frequency,
f
0
. The nominal frequency at any case
temperature,
T
C
, may be calculated from:
