SMD7050 21.4MHz RF Crystal Filter

High-precision 21.4MHz RF crystal filters in a 7050 SMD package, featuring a ±7.5kHz bandwidth and low insertion loss, specifically designed for IF (intermediate frequency) signal filtering in communication equipment. 

Features

Compact SMD Package: Utilizes standard 7050 (7.0x5.0mm) SMD packaging, ideal for high-density PCB layouts and automated assembly.

High Selectivity: Designed for 21.4MHz center frequency with a precise 3dB pass-band width of ≥±7.5kHz.

Low Signal Loss: Features low insertion loss (≤2.0dB) and minimal ripple (≤1.0dB) to ensure superior signal integrity.

Superior Interference Rejection: Offers high ultimate attenuation of up to 70dBc, effectively suppressing out-of-band noise and spurious signals.

Industrial-Grade Durability: Supports a wide operating temperature range from -40°C to +85°C, ensuring reliability in harsh environments.

Applications

Wireless Communication: Widely used in professional walkie-talkies, two-way radios, and mobile handheld terminals.

IF Signal Processing: Specifically designed for 21.4MHz IF (Intermediate Frequency) filtering in various radio receivers.

Communication Infrastructure: Suitable for wireless base stations, repeater systems, and wireless access networks.

Telemetry and Control: Applied in telemetry systems, industrial remote control, and data link signal purification.

RF Front-End Modules: Serves as a critical frequency selection component in RF front-ends to enhance system sensitivity and selectivity.
