TA2590A

Overview

TA2590A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by Tai-Saw Technology. It operates at a center frequency of 840.8 MHz with a bandwidth of 1.5 MHz. The component features a typical insertion loss of 2.3 dB and provides high attenuation, specified as 24 dB. Electrical performance includes passband limits defined by frequencies 839 MHz and 844.1 MHz. The device is packaged in a compact 6-SMD, No Lead surface-mount format suitable for automated assembly.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal filtering
• Designed for precise bandpass applications in the 840 MHz range
• Constructed in a lead-free surface-mount package

Applications

• RF signal processing in communication systems
• Frequency selection in wireless devices
• Base station and mobile phone front-end modules

Procurement Notes

Verify the specific datasheet version from Tai-Saw Technology to confirm current electrical tolerances and thermal specifications. Ensure that the 6-SMD footprint matches the target PCB layout. Confirm RoHS compliance status through official documentation prior to integration into final assemblies.

Selection Notes

Select TA2590A when a narrow 1.5 MHz bandwidth is required around 840.8 MHz. Consider this SAW filter over ceramic alternatives if lower insertion loss is critical. Evaluate the 6-SMD package size against available board space constraints.
