Product Overview
The MW4IC2020NBR1 is a three-stage wideband LDMOS integrated RF power amplifier IC manufactured by NXP Semiconductors (formerly Freescale). Operating from 1600MHz to 2400MHz, it delivers 20W PEP output power with 27–29 dB typical gain. This monolithic component integrates built-in 50Ω matching circuits, ESD protection and temperature compensation, housed in chassis-mount TO-272 WB-16 package for good thermal performance. Note: This device is obsolete and no longer in production, suitable only for equipment maintenance.
Core Advantages
3-Stage Integrated Amplifier Architecture
Combines pre-driver, driver and power stages on a single chip, providing high gain and simplifying RF layout design.
Built-in 50Ω Impedance Matching
On-chip matching reduces external passive components, shortens development cycles and saves PCB space.
