ACT43750-101SR

Overview

The Qorvo ACT43750-101SR is an RF switch IC functioning as a bias controller and sequencer for GaN power amplifiers. It features a single-pole configuration with a maximum insertion loss of 1.5 dB. The device operates at frequencies up to 2.05 MHz, with typical run and idle times capped at 30 ns. Packaged in a 37-pin QFN (5x5 mm) SMD/SMT footprint, it supports RoHS compliance and includes moisture sensitivity ratings.

Feature Summary

• Integrates drain switching and negative gate voltage regulation for ultra-fast RF GaN PA control
• Provides automatic sequencing and bias calibration capabilities
• Designed specifically for complementary use with GaN/GaAs power amplifier drivers

Applications

• GaN Power Amplifier bias control
• RF Gate driver circuits
• Radar system front-end management
• Wireless communication transmitter modules

Procurement Notes

Verify the specific suffix 'SR' against the manufacturer's latest datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the component meets current RoHS directives and check moisture sensitivity level (MSL) requirements for surface-mount assembly processes prior to procurement.

Selection Notes

Select this component when designing systems requiring precise timing and bias sequencing for GaN-based transmitters. Consider the 30 ns switching speed and 1.5 dB insertion loss metrics relative to system latency and signal integrity needs. Validate compatibility with the target GaN PA model, such as those paired with the ACT41000 series.
