TA1845D

Overview

The TA1845D is a Surface Acoustic Wave (SAW) filter manufactured by TST, designed for wireless RF applications. It operates at a center frequency of 2.14 GHz with a bandwidth of 60 MHz and an insertion loss of 2.5 dB. The component is housed in a 5-SMD, no-lead package, suitable for surface mount installation.

Feature Summary

• Engineered as a SAW filter for wireless radio frequency signal processing
• Optimized for operation within the 2.14 GHz frequency range
• Constructed in a compact surface-mount package for automated assembly

Applications

• Wireless communication systems
• RF front-end modules
• Signal filtering in transceivers

Procurement Notes

Verify the specific manufacturer designation, as TST may refer to Tai-Saw Technology or other entities. Confirm the package type matches the design requirements, noting variations such as 5-SMD configurations. Ensure the center frequency and bandwidth specifications align with the target application before procurement.

Selection Notes

Select this component for applications requiring a 2.14 GHz SAW filter with moderate insertion loss. Consider the 5-SMD package constraints during PCB layout. Evaluate power handling capabilities, as SAW filters typically have limited power tolerance compared to dedicated transmit filters.

Part Context

Tai-Saw Technology produces SAW filters for various wireless standards. The TA1845D belongs to their lineup of RF components targeting specific frequency bands. These devices are integral to modern wireless infrastructure and consumer electronics requiring precise frequency selection.

Replacement Considerations

Cross-reference with other 2.14 GHz SAW filters from manufacturers like Murata or Skyworks. Verify pinout compatibility and electrical parameters such as bandwidth and insertion loss when substituting.
