Hermetically sealed microstrip construction ensures environmental stability
High quality factor optimized for low-loss RF signal processing

Applications

RF phase shifters
Voltage-controlled oscillators
RF tunable filters

Procurement Notes

Verify the specific ordering suffix against official Microchip Technology documentation to ensure correct variant selection. Confirm that the hermetic microstrip package matches your PCB footprint requirements. Cross-reference datasheet electrical parameters with system design specifications before procurement to guarantee compatibility with operating voltage and frequency ranges.

Selection Notes

Select this component when high Q-factor and stable capacitance ratios are required in RF circuits. The GaAs material offers superior performance compared to silicon alternatives in high-frequency regimes. Ensure the 22V breakdown voltage aligns with peak reverse voltage limits in the target application circuit design.

Part Context

This part belongs to Microchip's discrete semiconductor portfolio, specifically within the varactor diode category. It serves as a critical passive component in microwave and RF integrated circuits, providing variable capacitance control essential for frequency modulation and tuning functions in communication systems.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements may not match the hermetic sealing or GaAs hyperabrupt characteristics. Verify pinout compatibility and thermal management requirements if substituting with similar surface-mount varactors.
