SAW Filters | SMD 5050 Ceramic SMD SAW Bandpass Filter

Core Advantages

• High Power Handling: Larger cavity than 3030/3838 packages provides ample RF power headroom; high-power TX loops won't saturate or distort — ideal for long-range wireless equipment.
• Ultra-High Out-of-Band Rejection: Excellent stopband attenuation effectively shields 2.4GHz WiFi and adjacent-channel spurious interference, significantly boosting receiver sensitivity and adjacent-channel selectivity.
• Differential / Single-Ended Dual Configurations: 8-Pin pad compatible with both single-ended and differential circuit topologies — one device fits multiple circuit designs.
• Full-Condition Coverage: Automotive-grade variants meet extreme cold/heat in-vehicle and outdoor field environments; one-stop coverage across commercial, industrial, and automotive scenarios.

Product Introduction

The SMD5050 is a 5.0×5.0mm leadless ceramic SMD SAW filter featuring a mainstream 8-Pin pad layout. Frequency coverage spans 76.5MHz to 1000MHz, with primary frequencies at 315 / 433 / 868 / 915MHz ISM, 1575MHz GNSS, and receiver IF from 70~300MHz. Standard 50Ω impedance with full high-speed SMT compatibility. The larger cavity over 3030/3838 delivers superior power headroom and out-of-band rejection performance.
