KW41Z Power Amplifier Reference Design

Overview

The KW41Z Power Amplifier reference design uses an external power amplifier to boost the transmitter output power to +20 dBm. This enables extended range for applications that require communications over long distances or in harsh RF environments.The reference design uses the KW41Z wireless MCU which is pin compatible with KW31Z and KW21Z devices. The KW41Z can easily be replaced with the desired device.
