TA1845A

Overview

The TA1845A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by TST. It operates at a center frequency of 2.14 GHz with a bandwidth of 60 MHz and insertion loss of 2.5 dB. The component is housed in a compact 5-SMD, No Lead package, specifically identified as SM5050-8PAD. Designed for RF applications, it supports mobile phone and LTE systems. The device complies with RoHS standards and utilizes surface mount technology for automated assembly.

Feature Summary

Surface Acoustic Wave (SAW) technology for efficient RF filtering
Compact SMD package suitable for space-constrained designs
RoHS compliant construction

Applications

Mobile phone RF front-end modules
LTE system signal processing
General wireless RF applications

Procurement Notes

Verify the specific datasheet version and customer part number approval status before procurement. Confirm that the SM5050-8PAD package matches the PCB footprint requirements. Ensure the 2.14 GHz center frequency aligns with the target application's spectral allocation. Check for any specific handling instructions related to the 5-SMD no-lead configuration during assembly.

Selection Notes

Select this component when a 60 MHz bandwidth at 2.14 GHz is required for SAW-based filtering. The 2.5 dB insertion loss offers a balance between signal attenuation and selectivity. The 5-SMD package facilitates high-volume surface mount production. Consider thermal management and impedance matching networks compatible with the specified package dimensions.

Part Context

TST specializes in SAW filters for communication and automation sectors. The TA1845A belongs to their RF filter portfolio targeting mobile and LTE infrastructure. Tai-Saw Technology Co., Ltd. produces these components for global electronic supply chains.

Replacement Considerations

No public substitute part numbers are confirmed for the TA1845A. Verify compatibility with alternative SAW filters offering identical 2.14 GHz center frequency and 60 MHz bandwidth if sourcing constraints exist.
