Procurement Notes

Verify the specific suffix codes against official Crystek documentation to ensure compatibility with required environmental ratings and packaging formats. Confirm that the selected variant meets the necessary RoHS compliance standards for your manufacturing process. Cross-reference the pinout configuration with your schematic design to prevent interface mismatches during assembly. Ensure that thermal management strategies align with the specified operating temperature range to maintain long-term reliability.

Selection Notes

Select this model when a fixed frequency range between 805 MHz and 815 MHz is required with minimal phase noise. Consider the 16-QFN package size if space constraints are critical for the application layout. Evaluate the tuning voltage linearity and pushing specifications against system sensitivity requirements. Compare the output power levels with downstream amplifier needs to determine if additional gain stages are necessary for optimal signal integrity.
