AM4000B1683

Overview

The AM4000B1683 is a ceramic bandpass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 4000 MHz with a bandwidth of 400 MHz. The device maintains an insertion loss of less than 1 dB and a VSWR of 1.5:1 within the passband range of 3800 MHz to 4200 MHz. It features a 50 Ohm impedance and provides rejection greater than 60 dB at 3000 MHz and 5000 MHz, with over 30 dB rejection at 3500 MHz and 4500 MHz. Mechanical specifications include through-hole mounting and dimensions of 1.25 x 0.38 x 0.38 inches. The operating temperature range is -25°C to +70°C.

Feature Summary

• Utilizes ceramic construction for stable RF filtering performance
• Provides high out-of-band rejection exceeding 60 dB at specified frequencies
• Designed for low insertion loss and minimal signal distortion in the passband
