UXM15P

Overview

The UXM15P is a programmable integer-N prescaler manufactured by Microchip Technology, designed for high-frequency RF applications. It operates from DC to 20 GHz with a specified functional range up to 15 GHz. The device supports division ratios of 2, 4, 5, 6, 7, 8, and 9. It requires a single -3.3 V supply voltage and draws 185 mA of operating current. The output power is rated at 3 dBm. Housed in a 24-pin QFN package with an exposed pad (QFN-24), it is suitable for surface-mount installation. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports multiple programmable integer division ratios including 2, 4, 5, 6, 7, 8, and 9
• Operates across a wide frequency spectrum from DC to 20 GHz
• Integrated biasing allows operation with a single -3.3 V supply
• Utilizes silicon technology for robust RF signal processing

Applications

• Frequency synthesizers in wireless communication systems
• RF test and measurement equipment requiring high-speed signal division
• Phase-locked loop (PLL) circuits in microwave transceivers
• Spectrum analyzers and signal generators

Procurement Notes

Verify the specific suffix (e.g., /TR) for tape-and-reel packaging requirements if applicable. Confirm RoHS compliance status through official Microchip documentation prior to integration. Check for moisture sensitivity level (MSL) handling instructions during storage and assembly. Ensure the design accommodates the 24-QFN thermal pad requirements for proper heat dissipation and electrical grounding.

Selection Notes

Select this component when a wide bandwidth covering DC to 20 GHz is required for integer-N division. Consider the -3.3 V supply constraint and 185 mA current draw for power budget calculations. The QFN-24 package necessitates careful PCB layout for RF performance and thermal management. Verify that the required division ratios (2, 4, 5, 6, 7, 8, 9) align with the system's frequency planning needs.

Part Context

The UXM15P belongs to the UXM series of prescalers from Microchip Technology. This series is engineered for high-performance RF and microwave integrated circuits. The device complements other RF components like amplifiers (e.g., UA5M15MP) in complete signal chain solutions. It is part of Microchip's portfolio of wireless and RF ICs designed for demanding communication standards.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate alternative prescalers from Microchip or other manufacturers based on frequency range, division ratios, and package compatibility. Cross-reference pinouts and electrical specifications carefully before substitution.
