This document is a technical parameter manual for the TFS 35B filter, which mainly includes measurement conditions, characteristic parameters, insertion loss, rated frequency, center frequency, pass band, amplitude ripple, bandwidth, relative attenuation, etc.
The TFS 35 B filter specification outlines the measurement conditions, key electrical characteristics, and performance limits of the filter. It includes insertion loss, nominal and centre frequencies, pass‑band width, amplitude ripple, and group‑delay figures measured at 25 °C with 0 dBm input power.
Additional sections describe the mechanical package, pin connections, stability tests (shock, vibration, temperature cycling), packaging format (tape & reel), and air‑reflow temperature profiles for soldering. Contact information for VI TELEFILTER and revision history are also provided.
