TR0119AA0090

Overview

The TR0119AA0090 is a Surface Acoustic Wave (SAW) filter manufactured by TST Semiconductor. This component operates within the 4600-4800 MHz frequency range, providing a bandwidth of 200MHz to 300MHz depending on specific configuration. It features an insertion loss of approximately 1.5dB to 2dB and offers attenuation levels of 30dB. The device is designed for robust performance across operating temperatures ranging from -40°C to +85°C or +105°C. Physically, it utilizes a compact package with dimensions of 15.9x4.5x4.4 mm, suitable for high-frequency RF applications requiring precise signal filtering.

Feature Summary

• Surface Acoustic Wave technology for high-frequency signal processing
• Compact physical footprint suitable for space-constrained designs
• Wide operational temperature tolerance for industrial environments

Applications

• RF front-end filtering in wireless communication modules
• Signal conditioning in high-frequency transceivers
• Band selection in mobile device antenna systems

Procurement Notes

Verify the exact center frequency and bandwidth specifications against the official TST datasheet prior to procurement, as variations exist between sources regarding the 200MHz versus 300MHz bandwidth rating. Confirm the maximum operating temperature rating (+85°C vs +105°C) matches your thermal design requirements. Ensure the package dimensions align with your PCB layout constraints. Cross-reference the part number with authorized distributors to confirm authenticity and availability status.

Selection Notes

Select this component when a SAW filter is required for the 4.6-4.8 GHz band with low insertion loss. Consider the trade-off between the specified attenuation levels and the desired signal integrity. Evaluate the thermal stability requirements of your application to determine if the standard or extended temperature grade is necessary. Compare the physical size against available board space to ensure compatibility with the 15.9x4.5x4.4 mm form factor.
