TA0409A

Overview

The TA0409A is a Surface Acoustic Wave (SAW) band-pass filter manufactured by Tai-Saw Technology Co., Ltd. It operates at a center frequency of 420 MHz with a bandwidth of 20 MHz. The device features an insertion loss of 3.5 dB and provides attenuation of 60 dB/58 dB. It is housed in a 10-SMD, no-lead package with dimensions of 7.0 x 5.0 mm. The component supports an operating temperature range from -25°C to +75°C.

Feature Summary

• Utilizes surface acoustic wave technology for RF signal filtering
• Designed as a band-pass filter for wireless applications
• Constructed in a compact SMD package without leads

Applications

• Wireless communication systems
• RF front-end modules
• Signal processing circuits requiring 420 MHz filtering

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Tai-Saw Technology or authorized distributors before procurement. Confirm that the 10-SMD package dimensions and pinout match the target PCB layout requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this component when a 420 MHz center frequency with 20 MHz bandwidth is required for RF filtering. Consider the 3.5 dB insertion loss and 60 dB attenuation characteristics for system link budget calculations. The SMD form factor suits automated surface-mount assembly processes.

Part Context

Tai-Saw Technology specializes in SAW components, including filters and resonators, for mobile phones, base stations, and wireless LANs. The TA0409A belongs to their RF SAW filter series, designed for high-performance communication applications requiring precise frequency selection.

Replacement Considerations

Cross-reference with other 420 MHz SAW filters if supply constraints exist. Verify electrical parameters such as bandwidth and insertion loss against alternative part numbers to ensure compatibility with existing circuit designs.
