BLM7G1822S-40ABY

Product Overview

BLM7G1822S-40ABY is a LDMOS RF power transistor / RF power amplifier device from Ampleon. In an RF design it is normally used as a final or driver PA device in a matched RF power stage, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

For this model, the key application data to verify are: cellular or ISM-band RF power stage; exact band follows the BLF/BLM base number; load-pull/reference-circuit gain and efficiency must be taken from the Ampleon datasheet, not estimated from package alone; and high-current LDMOS drain bias with thermal design requirement. Because RF amplifier parts are layout- and matching-sensitive, BLM7G1822S-40ABY should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
