SAW Filters | SMD 3030 Compact Ceramic SMD SAW Bandpass Filter

Core Advantages

• Compact Integration: 3.0mm square-shell compact package saves PCB area, ideal for ultra-thin device designs.
• Excellent RF Performance: Low insertion loss preserves RF transmit power; high out-of-band rejection blocks WiFi and spurious interference, boosting overall receiver sensitivity and dramatically reducing GPS drop-out rates in positioning devices.
• Multi-Grade Selection: Three product tiers — Consumer, Industrial, Automotive — covering everything from commercial to in-vehicle harsh-condition applications in one stop.

Product Introduction

The SMD3030 SAW filter is a 3.0x3.0mm six-pin SMD ceramic-packaged surface acoustic wave bandpass filter. Frequency coverage spans 300MHz to 2605MHz, with mainstream fixed frequencies at 315 / 433.92 / 868 / 915 / 1575.42 / 2450MHz. Featuring standard 50ohm impedance and full SMT reflow solder compatibility, it is the go-to miniaturized filtering device for RF front-end designs.
