ATR4252C-RAPW

RF Amplifiers Overview

The ATR4252C-RAPW is an RF amplifier IC manufactured by Microchip Technology, designed for AM and FM signal processing. It operates across two distinct frequency bands: 150kHz to 30MHz and 70MHz to 110MHz. The device provides a gain of 13.5dB at a test frequency of 100MHz. It is housed in a 28-VQFN (4x5) surface-mount package. The component is currently listed as obsolete.

RF Amplifiers Procurement Notes

Verify part status carefully as this component is marked obsolete. Confirm availability through secondary market channels or authorized distributors holding remaining stock. Ensure the 28-VQFN footprint matches your PCB design requirements before procurement.

RF Amplifiers Selection Notes

Select this component only if legacy compatibility with 150kHz–30MHz and 70MHz–110MHz bands is required. Consider the 13.5dB gain specification for signal chain budgeting. Evaluate alternative active components if new designs are permitted due to the obsolete status.

RF Amplifiers Part Context

This RF amplifier belongs to Microchip's portfolio of wireless communication components. It serves specialized roles in analog signal conditioning for broadcast frequencies. The specific RAPW suffix indicates the tape-and-reel packaging variant.

RF Amplifiers Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Engineers should evaluate functional equivalents from other manufacturers supporting similar AM/FM bandwidths and VQFN packages.
