The R5-434-5-20 is a SAW resonator manufactured by RF Solutions. SAW (Surface Acoustic Wave) resonators are passive electromechanical devices used primarily in radio frequency (RF) applications for frequency control and filtering. They offer stable and precise frequency characteristics and are commonly employed in wireless communication systems.

Applications:

• Remote keyless entry (RKE) systems
• Wireless remote control devices
• Garage door openers
• Tire pressure monitoring systems (TPMS)
• Security alarms

Features:

• Stable frequency
• Low insertion loss
• Small size
• Rugged construction
• Suitable for low power applications

Benefits:

• Provides reliable frequency control for RF transmitters and receivers
• Enables compact and efficient wireless system designs
• Offers stable performance over a wide temperature range
• Reduces overall system cost by eliminating the need for external tuning components
• Enhances the performance and reliability of wireless applications

Additional Details:

SAW resonators operate by converting electrical signals into mechanical waves on the surface of a piezoelectric substrate. These waves are then converted back into electrical signals at a specific resonant frequency. The R5-434-5-20 is designed to operate at a specific frequency band, which should be verified based on the application requirements. The device's compact size and low power consumption make it well-suited for portable and battery-powered wireless devices. Careful consideration of the impedance matching and circuit layout is important to optimize the performance of the SAW resonator in the RF circuit.
