The PA is implemented as a two-stage 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). With single low voltage supply of 3.3V 20dB power gain between 2.4-2.5GHz, at a low quiescent current of 65mA. For +19dBm OFDM output power (64QAM, 54Mbps), the PA provides a low EVM (Error-Vector Magnitude) of 3.0%, and consumes 120mA total DC current with the nominal 3.3V bias. With increased bias of 4.5V EVM is ~ 5% at 23dBm. The LX5510 is available in a 16-pin 3mmx3mm micro-lead package (MLP). The compact footprint, low profile, and excellent thermal capability of the MLP package makes the LX5510 an ideal solution for medium-gain power amplifier requirements for IEEE 802.11b/g applications W WW .

This pin is DC-shorted to GND but AC-coupled to the transistor base of the first stage. Bias current control voltage for the first stage. Bias current control voltage for the second stage. The VB2 pin can be connected with the first stage control voltage (VB1) into a single reference voltage (referred to as Vref) through an external resistor bridge. Supply voltage for the bias reference and control circuits. This pin can be combined with both VC1 and VC2 pins, resulting in a single supply voltage (referred to as Vc). RF output for the power amplifier. Power supply for first stage amplifier. The VC1 feedline should be terminated with a 4pF bypass capacitor 50mil apart from the device, followed by a 8.2nH blocking inductor at the supply side. This pin can be combined with VC2 and VCC pins, resulting in a single supply voltage (referred to as Vc). Power supply for second stage amplifier. The VC2 feedline should be driven with a 8.2nH AC blocking inductor and 1uF bypass capacitor. This pin can be combined with VC1 and VCC pins, resulting in a single supply voltage (referred to as Vc). The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power amplifier.
