The SAYRF1G95HG0F0AR1S is a SAW (Surface Acoustic Wave) filter manufactured by Murata Electronics North America. SAW filters are utilized in radio frequency (RF) applications to selectively pass or reject signals within a specific frequency range. This particular filter operates at approximately 1.95 GHz.

Applications

• Mobile communication devices (smartphones, tablets)
• Wireless infrastructure (base stations, repeaters)
• Wireless LAN (WLAN) devices (Wi-Fi routers, access points)
• GPS receivers
• RF front-end modules

Features

• High selectivity: Provides excellent rejection of unwanted signals outside the passband.
• Low insertion loss: Minimizes signal attenuation within the desired frequency range.
• Compact size: Suitable for integration into space-constrained applications.
• Surface Mount Technology (SMT): Facilitates automated assembly processes.
• Stable performance over temperature: Ensures reliable operation across a wide temperature range.
• RoHS compliant: Meets environmental standards for hazardous substances.

Benefits

• Improved signal quality: Filters out unwanted noise and interference, enhancing the signal-to-noise ratio (SNR).
• Enhanced system performance: Enables more reliable and efficient wireless communication.
• Reduced interference: Prevents unwanted signals from interfering with the desired signal.
• Smaller product size: The compact size of the filter contributes to the miniaturization of electronic devices.
• Lower manufacturing costs: SMT packaging facilitates automated assembly, reducing labor costs.
• Environmentally friendly: RoHS compliance ensures adherence to environmental regulations.

Additional Details

The SAYRF1G95HG0F0AR1S typically uses a piezoelectric substrate material, such as lithium tantalate (LiTaO3) or lithium niobate (LiNbO3), to achieve high performance. The filter's characteristics, including center frequency, bandwidth, insertion loss, and rejection, are carefully designed to meet the requirements of the application. Precise technical specifications, including impedance matching, ripple, and temperature coefficients, are available in the product datasheet from Murata. This is a surface mountable device typically attached using solder reflow.
