The FI168L0628M4-T is a SAW (Surface Acoustic Wave) filter manufactured by Taiyo Yuden. It is designed for RF applications, specifically for filtering signals at a particular frequency band around 628 MHz. These filters are used to selectively pass signals within a desired frequency range while attenuating unwanted signals outside that range.
Applications:
- Cellular Communication Systems: Used in mobile phones and base stations to filter specific frequency bands.
- Wireless Data Transmission: Employed in wireless modems and routers for clean signal transmission.
- GPS Receivers: Integrated into GPS devices to improve signal reception.
- RF Transceivers: Utilized in various RF transceivers to eliminate unwanted frequencies.
- Radio Broadcasting Equipment: Used to refine the output signal of radio transmitters.
Features:
- Precise Frequency Filtering: Accurately filters signals within a specific frequency range.
- Low Insertion Loss: Minimizes signal attenuation within the passband.
- High Attenuation: Effectively rejects signals outside the passband.
- Compact Size: Available in a small surface-mount package.
- Surface Mount Technology (SMT): Compatible with automated assembly processes.
Benefits:
- Enhanced Signal Clarity: Improves the quality of transmitted and received signals.
- Reduced Interference: Minimizes the impact of unwanted signals on desired signals.
- Improved System Performance: Increases the overall efficiency and reliability of wireless systems.
- Simplified Design: Easy integration into RF circuits.
- Cost-Effective Solution: Provides high performance at a competitive price.
Additional Details:
The FI168L0628M4-T SAW filter has a center frequency of approximately 628 MHz. It exhibits low insertion loss, typically less than 3 dB, and high attenuation in the stopband, often greater than 20 dB. It's designed for surface mount assembly. The operating temperature range usually spans from -40°C to +85°C. Proper impedance matching is crucial, often requiring a 50-ohm impedance. The datasheet should be consulted for precise electrical characteristics and PCB layout recommendations.
