Procurement Notes

Verify that the specific part number matches the required frequency range and control voltage specifications before procurement. Confirm compliance with RoHS3 standards if environmental regulations apply to your project. Ensure the 16-QFN footprint dimensions align with your PCB layout constraints. Check for recent date codes to guarantee component freshness and reliability. Validate that the supply voltage requirements are compatible with your system's power architecture.

Selection Notes

Select this component when a precise microwave frequency between 4.267 GHz and 4.442 GHz is required. Consider the 0.1 V to 16 V control voltage range for compatibility with your tuning circuitry. Evaluate the ±5 dBm output power against your system's gain requirements. The wide operating temperature range makes it suitable for harsh environments. Ensure the 10 pF load capacitance matches your resonant circuit design needs.
