TA1808A

Overview

The TA1808A is a Surface Acoustic Wave (SAW) band-pass filter manufactured by TST. It operates at a center frequency of 440 MHz with a bandwidth of 20 MHz. The device features an insertion loss of 2.4 dB and is designed for a 50-ohm system impedance. It is housed in a compact 6-SMD, no-lead package measuring 3.00mm x 3.00mm with a maximum height of 1.40mm. This component is RoHS compliant and intended for general-purpose RF applications requiring precise signal filtering.

Feature Summary

• Surface Acoustic Wave technology for efficient RF signal processing
• Band-pass frequency response centered at 440 MHz
• Compact surface-mount design suitable for space-constrained layouts

Applications

• General purpose RF filtering
• Embedded systems
• Industrial automation electronics

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Ensure the 6-SMD package dimensions align with your PCB footprint requirements. Confirm that the 2.4 dB insertion loss meets your system's power budget constraints. Validate the 440 MHz center frequency against your target application spectrum to avoid interference issues.

Selection Notes

Select the TA1808A when a 440 MHz center frequency and 20 MHz bandwidth are required for RF signal conditioning. Consider this component if a low-profile 3.00mm x 3.00mm SMD package is necessary for board real estate optimization. Evaluate the 2.4 dB insertion loss against system sensitivity requirements. Ensure compatibility with 50-ohm circuit designs and surface-mount assembly processes.
