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擄C or less. Aging may exceed the specification for prolonged
temperatures above +65擄C. Typically, aging is greatest the first
year after manufacture, decreasing in subsequent years.

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: f = f
0
[1 - FTC (T
0
- T
