Procurement Notes

Verify the specific manufacturer designation, as Tusonix products are often distributed under the CTS Electronic Components brand name. Confirm that the required RoHS compliance status aligns with project specifications, as documentation indicates varying compliance information across different sources. Ensure the selected variant matches the required 50 Ohm impedance and 1.5754 GHz center frequency for proper system integration.

Selection Notes

Select this component when a dedicated ceramic bandpass filter is required for L-band GPS frequencies. The choice depends on the need for a monoblock solution offering precise 11 MHz bandwidth filtering. Consider the physical dimensions and surface-mount termination style for PCB layout compatibility. This part is suitable for both commercial and military-grade navigation equipment requiring robust signal isolation.
