TB1338A

Overview

The TB1338A is a Surface Acoustic Wave (SAW) filter manufactured by TST. It operates at a center frequency of 380.75 MHz, designed for pager RF applications. The component features a bandwidth of 300 kHz and an insertion loss of 3.3 dB. It utilizes an 8-SMD, no-lead package with dimensions of 3.80mm x 3.80mm.

Feature Summary

• Surface Acoustic Wave technology for signal filtering
• Optimized for pager radio frequency applications
• Compact surface mount packaging

Applications

• Pager RF systems
• Wireless communication devices
• RF signal processing modules

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pin configurations. Ensure compatibility with existing PCB footprints, as the 8-SMD no-lead package requires precise soldering profiles. Confirm that the 380.75 MHz center frequency aligns with the target system requirements before integration.

Selection Notes

Select this component when a narrow 300 kHz bandwidth is required for 380.75 MHz signals. The low insertion loss of 3.3 dB supports efficient signal transmission. Consider the small 3.8x3.8 mm footprint for space-constrained designs in portable communication equipment.

Part Context

TST specializes in SAW components for wireless communications. This filter belongs to their RF SAW series, targeting niche markets like paging systems. The company provides both RF and IF SAW filters for various mobile and fixed communication standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other 380.75 MHz SAW filters if sourcing alternatives.
