LX5514M ® TM InGaP HBT 2.4 – 2.5 GHz Power Amplifier P RODUCTION D ATA S HEET KEY FEATURES DESCRIPTION LX5514M also features an on-chip power detector at the output port of the PA to help reduce BOM cost and PCB space for implementation of power control in a typical wireless system. The LX5514M is available in a 6pin 1.5mm x 1.5mm dual flat no lead package (DFN 1.51.5mm2-6L). The compact footprint, low profile, and excellent thermal capability make the LX5514M an ideal solution for 802.11b/g/n applications. Advanced InGaP HBT 2.4-2.5GHz Operation Single-Polarity 3.3V Supply Quiescent Current ~ 84mA Power Gain ~ 27dB 19dBm @3% EVM/3.3V Total Ic ~ 130mA @19dBm/3.3V Complete On-Chip Input Match Simple Output Match 2 Small Footprint: 1.5x1.5mm Low Profile: 0.4mm W W W. Microsemi .CO M The LX5514M is a power amplifier optimized for WLAN(802.11b/g/n) applications in the 2.4-2.5 GHz frequency range. The PA is implemented as a two-stage monolithic microwave integrated circuit (MMIC) with active bias, on-chip input matching, and output pre-matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates with a single positive voltage supply of 3.3V, and provides power gain of 27dB and output powers of 19dBm at 3.3V for 3% EVM in the 2.4-2.5GHz.
