RMPA2450

RMPA2450 May 2004 RMPA2450 2.4–2.5 GHz GaAs MMIC Power Amplifier General Description The Fairchild RMPA2450 is a fully monolithic power amplifier in a surface mount package for use in wireless applications in the 2.4 to 2.5GHz ISM frequency band. The amplifier may be biased for linear, class AB or class F for high efficiency applications. On-chip matching components allow operation in a 50Ω system with no external matching components. The MMIC chip design utilizes our 0.25µm power PHEMT process.
