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

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

+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.
