The LX5512B is available in a 16pin 3mmx3mm micro-lead package (MLP). The compact footprint, low profile, and excellent thermal capability of LX5512B meets the requirements of high-gain power amplifiers for IEEE 802.11b/g applications. Advanced InGaP HBT 2.4-2.5GHz Operation Single-Polarity 3.3V Supply Low Quiescent Current ICQ ~65mA Power Gain ~ 32 dB at 2.45GHz & Pout=19dBm Total Current ~140mA for Pout=19dBm at 2.45 GHz OFDM EVM ~3 % for 64QAM/ 54Mbps & Pout=19dBm Small Footprint: 3x3mm2 Low Profile: 0.9mm WWW . Microsemi .C OM The LX5512B is a power amplifier optimized for WLAN applications in the 2.4-2.5 GHz frequency range. The PA is implemented as a threestage monolithic microwave integrated circuit (MMIC) with active bias and input/output pre-matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates at a single low voltage supply of 3.3V with 32 dB power gain between 2.4-2.5GHz, at a low quiescent current of 65mA.

FUNCTIONAL PIN DESCRIPTION Name Description RF IN RF input for the power amplifier. This pin is directly connected to base, a 10pF decoupling capacitor may be needed. VB12 Bias current control voltage for the first and second stage. VB3 Bias current control voltage for the third stage. The VB3 pin can be connected with the first and second stage control voltage (VB12) into a single reference voltage (referred to as VREF) through an external resistor bridge. VCC Supply voltage for the bias reference and control circuits. The VCC feed line should be terminated with a 10nF bypass capacitor close to connector pin. This pin can be combined with VC1, VC2 and VC3 pins, resulting in a single supply voltage (referred to as VC). RF OUT RF output for the power amplifier. This pin is DC-decoupled from the transistor collector of the third stage. Power supply for first stage amplifier. The VC1 feed line should be terminated with a 10pF bypass capacitor, followed by a 36 Ohm resistor. This pin can be combined with VC2,VC3 and VCC pins, resulting in a single supply voltage (referred to as VC). VC2 Power supply for second stage amplifier. The VC2 feed line should be terminated with a 18pF bypass capacitor. This pin can be combined with VC1,VC3 and VCC pins, resulting in a single supply voltage (referred to as VC). VC3 Power supply for the third stage amplifier. The VC3 feed line should be terminated with 27 pF and 10 nF bypass capacitors. This pin can be combined with VC1,VC2 and VCC pins, resulting in a single supply voltage (referred to as VC). REF Power detector reference output pin should be terminated with a 100KΩ loading resistor DET Power detector output pin should be terminated with a 100KΩ loading resistor GND The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power amplifier.
