LX5551 is a high-performance WLAN front-end module (FEM) for 802.
11b/g/n and other applications in the 2.
4-2.
5GHz frequency range.
LX5551 integrates an advanced InGaP/GaAs Heterojunction Bipolar
Transistor (HBT) power amplifier with both input/output impedance matching, and an InGaAs pseudomorphic HEMT (pHEMT) switch, into a single 3x3mm package.
The Tx path of LX5551 features a two-stage monolithic microwave integrated circuit (MMIC) power amplifier with active bias circuitry, and 50 Ω input/output...
