Overview
The KV1993A-150A is a silicon tuning varactor diode manufactured by Microchip Technology, designed for voltage-controlled capacitance applications in RF and microwave circuits. It utilizes an EPSM (Epitaxial Planar Super Abrupt) hyperabrupt junction structure to achieve high tuning sensitivity. The component is supplied as a non-hermetic die in Surface Mount Technology (SMT) format, originating from the United States. This configuration supports integration into compact RF modules and RFID integrated circuits where precise frequency tuning is required.
Feature Summary
- EPSM hyperabrupt junction structure for enhanced voltage-controlled capacitance performance
- Non-hermetic silicon die construction optimized for SMT integration
- Designed specifically for RF and microwave circuit tuning applications
Applications
- RF module frequency tuning
- RFID integrated circuit design
- Microwave circuit voltage-controlled capacitance adjustment
Procurement Notes
Verify that the specific procurement requirement aligns with the non-hermetic die form factor rather than a packaged component. Confirm that the application environment can accommodate bare die mounting processes. Ensure compatibility with the intended SMT assembly workflow. Check for any specific handling requirements associated with unprotected silicon dies during storage and installation.
Selection Notes
Select this component when high tuning sensitivity is critical for RF or microwave designs. The EPSM technology offers superior performance compared to standard abrupt junctions. Consider the bare die format for space-constrained PCB layouts. Evaluate thermal management strategies suitable for direct die attachment methods.
Part Context
This part belongs to Microchip's portfolio of discrete diodes and rectifiers, specifically focusing on tuning varactors. It complements the company's broader offerings in interface technologies and embedded control systems. The product line targets high-growth markets including automotive, industrial, and IoT applications requiring precise signal conditioning.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative suppliers.
