DESCRIPTION

The LX5514 is a power amplifier optimized for WLAN applications in the 2.3 – 2.5GHz frequency range. The power amplifier is implemented as a two-stage monolithic microwave integrated circuit (MMIC) with active bias and output pre-matching.

The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). Power gain of 28dB is obtained with a low quiescent current of 80mA.
