PE45361A-X

Overview

The PE45361A-X is a HaRP™ technology-enhanced power limiter designed for high-performance applications in test and measurement equipment, wireless infrastructure transceivers, and antennas. Operating within a frequency range of 10MHz to 6GHz, it provides a monolithic alternative to PIN diode limiters without requiring external bias components. The device features a compact 3mm x 3mm QFN-12 package and offers dual-mode operation including power limiting and power reflection modes.

Feature Summary

• HaRP™ technology-enhanced UltraCMOS construction providing GaAs-like performance with CMOS integration
• Dual-mode operation supporting both power limiting and power reflection functionalities
• Adjustable input 1dB compression point or limiting threshold via low control voltage
• Fast response and recovery time of less than 1ns

Applications

• Test and measurement equipment
• Wireless infrastructure transceivers
• Antenna systems

Procurement Notes

Verify the specific suffix 'A-X' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering information matches the exact RoHS status and packaging type required for your assembly process. Cross-reference the part number with official pSemi documentation to avoid substitution errors with similar family members.

Selection Notes

Select this component when a monolithic solution replacing discrete PIN diodes is required to reduce design complexity. It is suitable for applications needing adjustable limiting thresholds between +7dBm and +13dBm. Consider the 3x3mm QFN package constraints and the need for a control voltage interface for threshold adjustment during circuit design.

Part Context

This device belongs to the PE45xxx series of UltraCMOS power limiters manufactured by pSemi. It utilizes Peregrine’s proprietary SOI-based UltraCMOS process. The series includes variants like the PE45140 and PE45450, differentiated primarily by their frequency ranges and power handling capabilities, all sharing the core benefit of eliminating external bias networks.
