DEA203750BT-2292A1-H

Overview

The TDK DEA203750BT-2292A1-H is a surface-mount bandpass filter designed for RF signal conditioning. It operates at a center frequency of 3.75 GHz with a bandwidth of 900 MHz, covering the 3300–4200 MHz range. The component features a 50 Ohm impedance and an insertion loss of 2.3 dB. Housed in a compact 0805 (2.0 mm x 1.25 mm) package, it supports operation between -40°C and +85°C. Key attenuation specifications include minimum rejection of 43 dB at 100–915 MHz, 1427–1467 MHz, and 45 dB at 1627–1661 MHz.

Feature Summary

• Provides effective EMI/RFI suppression through high attenuation in specific lower frequency bands
• Optimized for 5G Low Band N77 applications with precise center frequency tuning
• Utilizes multilayer ceramic technology for reliable surface-mount integration

Applications

• 5G Low Band N77 mobile communication devices
