2.

Unless noted otherwise, all measurements are made with the filter

installed in the specified test fixture that is connected to a 50

Ω test

system with VSWR

≤ 1.2:1. The test fixture L and C are adjusted

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.

temperatures above +65

year after manufacture, decreasing in subsequent years.

The specifications of this device are based on the test circuit

shown above and subject to change or obsolescence without

notice.

7.

All equipment designs utilizing this product must be approved by

the appropriate government agency prior to manufacture or sale.
