WWW.Microsemi .COM LX5540 LX5540 LX5540 Co-Package 2.3 2.5 GHz HBT Power TM Amplifier & pHEMT Low Noise Amplifier PRODUCTION DATA SHEET DESCRIPTION KEY FEATURES LX5540 is a co-package RFIC For 20dBm OFDM output power Advanced InGaP HBT consisting of an InGaP/GaAs (64QAM, 54Mbps), the PA provides a 2.3-2.5GHz Operation Heterojunction Bipolar Transistor low EVM (Error-Vector Magnitude) of Single-Polarity 3.3V (HBT) power amplifier and a InGaAs 3%, and consumes 145 mA total DC Supply Enhancement mode pseudomorphic current. Quiescent Current 80mA HEMT (E-pHEMT) low noise The LNA offers 14 dB gain, 1.5 dB Power Gain 28 dB amplifier. Both are optimized for noise figure and a high input IP3 of +4 Total Current 145mA for WLAN applications in the 2.3-2.5 dBm at 10 mA of DC current. Pout=20 dBm OFDM GHz frequency range. The PA is LX5540 is available in a 16-pin EVM~3% at 20dBm implemented as a two-stage 3mmx3mm micro-lead package 54Mbps /64QAM monolithic microwave integrated (MLPQ-16L). The compact footprint, LNA Gain ~ 14 dB circuit (MMIC) with active bias and low profile, and thermal capability of LNA Noise Figure ~ 1.5dB output pre-matching. The LNA is fully the MLP package makes the LX5540 an LNA Input IP3 ~ +4dBm matched internally and no external ideal solution for medium-gain power On-Chip Bias Circuit matching circuit is required. transmitter and very low noise receiver On-Chip Input/Output Both devices operate with single requirements for IEEE 802.11b/g Match 2 low voltage supply of 3.3V. The PA applications. Small Footprint: 3x3mm offers 28 dB power gain between 2.3- Low Profile: 0.45mm 2.5GHz, at a low quiescent current of 80mA.
