Procurement Notes
Verify the specific package variant, such as SM3030-6PAD, against schematic requirements. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Ensure the manufacturer designation matches TST or Tai-Saw Technology Co., Ltd. to avoid counterfeit components. Cross-reference datasheet electrical parameters with system specifications before finalizing procurement orders.
Selection Notes
Select this component when a SAW filter is required for 1.57GHz GPS signals. Consider the 4.2dB insertion loss impact on overall link budget. The 80MHz bandwidth must align with the desired channel selectivity. Evaluate the 6-SMD footprint compatibility with existing PCB layout constraints and automated assembly capabilities.
Part Context
TST, also known as Tai-Saw Technology, specializes in SAW components for mobile phones, wireless LANs, and GPS devices. The company has historical ties to Motorola communication parts divisions. This product line supports various 3C products including remote controls and tire pressure sensors, focusing on RF front-end solutions for consumer electronics.
Replacement Considerations
Check for direct substitutes within the TST TA series that share identical 1.57GHz frequency and 6-pin SMD packaging. Verify pinout compatibility and mechanical dimensions before swapping manufacturers. Ensure alternative parts meet the same 80MHz bandwidth and insertion loss specifications.
