Procurement Notes

Verify the specific ordering suffix against official Crystek documentation to ensure correct pinout and performance characteristics. Confirm that the 16-QFN variant matches your PCB footprint requirements. Check RoHS3 compliance status if required by your manufacturing standards. Ensure the tuning voltage range aligns with your system's control interface capabilities before finalizing procurement.

Selection Notes

Select this component when a fixed center frequency near 1770 MHz is required with precise voltage control. Consider the 2.5 dBm output power level for direct drive applications or subsequent amplification needs. Evaluate the -120 dBc/Hz phase noise specification against system sensitivity requirements. Verify that the 12.7mm square package fits within the available board space constraints.
