PE64102B-Z

Overview

The PE64102B-Z is a DuNE-enhanced digitally tunable capacitor based on UltraCMOS technology. It operates within a frequency range of 100 MHz to 3 GHz, providing a capacitance range of 1.88 pF to 14 pF. The device features an SPI interface for digital control and utilizes a surface-mount UFQFN-12 package measuring 2 mm x 2 mm with a height of 0.55 mm. It supports a DC voltage rating of 2.8 VDC and maintains a minimum Q factor of 50 at test frequencies between 470 MHz and 582 MHz. The component functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates seamless tuning capabilities across the 100 MHz to 3 GHz spectrum using DuNE technology
• Enables precise digital adjustment via standard SPI interface without manual calibration
• Delivers high performance with a minimum Q factor of 50 in specified RF applications

Applications

• RF impedance matching networks
• Antenna tuning systems
• Phase shifters in beamforming arrays

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's current datasheet to confirm RoHS compliance status and lead time requirements. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Confirm that the SPI protocol implementation aligns with the controller specifications before finalizing procurement orders.

Selection Notes

Select this component when digital control over capacitance values is required within the 1.88 pF to 14 pF range. It is suitable for designs needing a compact 2 mm x 2 mm footprint and operation up to 3 GHz. Consider the 2.8 VDC limit and -40°C to +85°C temperature range during thermal and power budgeting.

Part Context

This part belongs to the UltraCMOS family of digitally tunable capacitors manufactured by pSemi. It represents a monolithic integration solution designed to replace traditional varactor diodes or mechanical variable capacitors in modern RF front-end modules.

Replacement Considerations

PE64102 serves as the base model identifier. Verify if non-'Z' suffix variants differ in packaging or environmental compliance before substitution.
