This dual-band bandpass filter is specifically designed for GPS and other satellite positioning systems, covering both L1 (1575 MHz) and L2 (1227 MHz) frequency bands. Built with advanced SAW (Surface Acoustic Wave) technology, it ensures precise bandwidth control and excellent cutoff characteristics, effectively eliminating out-of-band interference. Ideal for enhancing the anti-jamming performance of satellite navigation receivers.
Features:
1.Dual-Band Coverage: Supports L1 (1575 MHz) and L2 (1227 MHz) signals simultaneously.
2.Low Insertion Loss: ≤4.0 dB in passband for minimal signal attenuation.
3.High Precision: Sharp roll-off and stable performance with SAW technology.
4.Robust Design: SMA-F connectors, compact size, and lightweight for easy integration.
