The CU452A1F-897.5-1TE2 is a surface acoustic wave (SAW) filter manufactured by TDK Corporation. SAW filters are used in radio frequency (RF) applications to selectively pass or reject signals within a specific frequency range. They are commonly employed in communication systems to filter unwanted signals and improve signal quality. This particular component is likely designed for a specific frequency around 897.5 MHz.

Applications

• Cellular Communication Systems: Used in mobile phones and base stations to filter RF signals.
• Wireless Communication Systems: Employed in Wi-Fi, Bluetooth, and other wireless devices.
• GPS Receivers: Filters signals from GPS satellites for accurate positioning.
• Remote Control Systems: Used to filter signals in remote control transmitters and receivers.
• Television Broadcasting: Filters signals in television tuners.

Key Features

• High Selectivity: Provides sharp rejection of unwanted signals.
• Low Insertion Loss: Minimizes signal attenuation within the passband.
• Surface Mount Technology (SMT): Facilitates automated assembly and high-density board layouts.
• Compact Size: Enables miniaturization of electronic devices.
• Stable Performance: Ensures consistent performance over a wide temperature range.

Benefits

Additional Details

The 'CU' prefix could refer to a specific series of SAW filters from TDK. '452A1F' likely denotes specific design characteristics of the filter. '897.5' specifies the center frequency in MHz around which the filter operates. '1TE2' could be a specific version or manufacturing code. SAW filters operate by converting electrical signals into mechanical waves on a piezoelectric substrate. These mechanical waves are then converted back into electrical signals at the output. The design of the interdigital transducers (IDTs) on the substrate determines the filter's frequency response.

For precise specifications, including insertion loss, bandwidth, rejection, impedance, and package dimensions, refer to the official TDK datasheet for the CU452A1F-897.5-1TE2. Impedance matching is crucial for optimal performance of SAW filters.
