TA1669A

Overview

The TA1669A is a general-purpose RF Surface Acoustic Wave (SAW) filter manufactured by TST. It operates at a center frequency of 1725 MHz with a bandwidth of 20 MHz. The device features an insertion loss of 3 dB and is housed in a compact 6-SMD, No Lead package measuring 3.00mm x 3.00mm. It supports surface mount assembly and is rated for input power levels up to 10 dBm.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal filtering
• Designed as a general-purpose band pass filter
• Compact surface mount package suitable for space-constrained designs

Applications

• RF front-end modules requiring 1725 MHz filtering
• Wireless communication systems operating in the specified frequency band
• General purpose RF signal processing circuits

Procurement Notes

Verify the specific datasheet revision and electrical characteristics against the manufacturer's official documentation before integration. Confirm that the 6-SMD package dimensions and pinout match the target PCB layout requirements. Ensure thermal management aligns with the specified operating temperature range of -40°C to +85°C during system design.

Selection Notes

Select this component when a SAW filter is required for the 1725 MHz frequency range with a 20 MHz bandwidth. Consider the 3 dB insertion loss and 10 dBm input power rating relative to system signal levels. The choice depends on the availability of the 6-SMD package format within the mechanical constraints of the application.
