The FAR-D6JH-2G1400-B1BT is a SAW (Surface Acoustic Wave) filter manufactured by Taiyo Yuden. This filter is designed to operate at a center frequency of 2.14 GHz and is commonly used in wireless communication systems to selectively pass or reject signals within a specific frequency range.

Applications:

• Mobile phones: Filtering of RF signals in cellular communication bands, specifically for 4G LTE and 5G NR applications.
• Wireless LAN (WLAN): Filtering of signals in Wi-Fi devices to improve signal quality and reduce interference.
• Global Positioning System (GPS): Filtering of GPS signals to enhance accuracy and reliability.
• Bluetooth devices: Filtering of Bluetooth signals for improved communication performance.
• Satellite communication systems: Filtering of signals in satellite receivers and transmitters.

Features:

• High selectivity: Provides sharp cutoff characteristics to effectively filter out unwanted signals.
• Low insertion loss: Minimizes signal attenuation within the passband, preserving signal strength.
• Small package size: Compact design allows for integration into space-constrained devices.
• Surface mount technology (SMT): Designed for easy and efficient mounting on printed circuit boards (PCBs).
• RoHS compliant: Meets Restriction of Hazardous Substances directives for environmental compliance.

Benefits:

• Improved signal quality: Filters out unwanted noise and interference, enhancing the clarity and strength of the desired signal.
• Enhanced communication performance: Improves the range and reliability of wireless communication systems.
• Reduced interference: Minimizes the impact of unwanted signals on other electronic devices.
• Simplified design: Easy to integrate into various systems due to its standard SMT package.

Specifications:

Typical specifications include a center frequency of 2.14 GHz, a bandwidth of approximately 75 MHz, an insertion loss of less than 2.0 dB, and an attenuation of greater than 40 dB at frequencies outside the passband. Impedance is usually 50 ohms. Check the Taiyo Yuden datasheet for confirmed performance data.

In summary, the FAR-D6JH-2G1400-B1BT SAW filter from Taiyo Yuden provides high selectivity and low insertion loss at 2.14 GHz, making it an excellent choice for filtering RF signals in various wireless communication applications.
