The frequency fC is defined as the midpoint between the 3dB frequencies. 2. 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, fC. Note 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. Phone: +86 10 6301 4184 S Fax: +86 10 6301 9167 © April 2004 by Vanlong Technology Co., Ltd. F 5 4.
