TA0440A

Overview

The TA0440A is a Surface Acoustic Wave (SAW) bandpass filter manufactured by TST Tai-Saw Technology Co., Ltd. Designed for GPS applications, it operates at a center frequency of 1575.42 MHz with a bandwidth of 2 MHz. The device features an insertion loss of typically 2.9 dB and a maximum input power rating of 10 dBm. It utilizes a 6-SMD, no-lead package with dimensions of 3.0x3.0 mm. Electrical specifications include a DC voltage withstand limit of 5 V and a nominal impedance of 50 Ω. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise signal filtering in the L1 GPS band
• Compact surface-mount design facilitates integration into space-constrained electronic assemblies
• Optimized for low insertion loss to maintain signal integrity in receiver front-ends

Applications

• GPS receiver modules
• Satellite positioning systems
• Wireless communication devices requiring L1 band filtering

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel configuration, as packaging variations may exist. Ensure the requested part matches the exact center frequency and bandwidth requirements for the target GPS application. Confirm compliance with current environmental regulations such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when a compact SAW filter is required for the 1575.42 MHz GPS frequency band. Consider the 3.0x3.0 mm footprint for board space constraints. Evaluate the 2.9 dB typical insertion loss against system link budget requirements. Ensure the operating temperature range meets the environmental conditions of the end product.

Part Context
