Overview
The TA0232A is a Surface Acoustic Wave (SAW) band-pass filter manufactured by TST. It operates at a center frequency of 1090 MHz with a bandwidth of 12 MHz. The device features an insertion loss of 3.9 dB and provides high attenuation in stopbands, specifically 36 dB, 43 dB, 47 dB, 48 dB, and 50 dB. It is housed in an SMD 3.8x3.8 mm package with an 8-pin configuration (S3838-8P). The component supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Utilizes Surface Acoustic Wave technology for RF signal filtering
- Designed as a band-pass filter for specific frequency selection
- Constructed in a compact surface-mount device package
Applications
- Wireless communication systems
- Mobile phone base stations
- GPS receivers
- Satellite digital broadcasting equipment
Procurement Notes
Verify the exact datasheet version when sourcing, as specifications may vary slightly between revisions. Confirm the package type matches the required PCB footprint, specifically the S3838-8P configuration. Ensure the supplier provides RoHS compliance documentation if environmental regulations apply to the manufacturing process. Cross-reference the part number TA0232A with official TST catalogs to confirm current lifecycle status and availability.
Selection Notes
Select this component when a precise 1090 MHz center frequency is required with a narrow 12 MHz bandwidth. The low insertion loss of 3.9 dB makes it suitable for applications where signal integrity is critical. Consider the thermal range of -40°C to +85°C for industrial or automotive environments. The SMD form factor facilitates automated assembly in compact electronic designs.
