The low EVM (Error-Vector Magnitude) of Low Quiescent Current Icq PA is implemented as a two-stage 3.0%, and consumes 125 mA total DC ~65mA monolithic microwave integrated current with the nominal 3.3V bias. Power Gain ~20dB 2.45GHz circuit (MMIC) with active bias and With increased bias of 5 V EVM is ~ and Pout = 19dBm input/output pre-matching. 4% at 23 dBm. Total Current 125mA for Pout = The device is manufactured with an The LX5510 is available in a 16-pin 19dBm 2.45GHz OFDM InGaP/GaAs Heterojunction Bipolar 3mmx3mm micro-lead quad package EVM ~ 3.0% for 64QAM / 54Mbps and Pout = 19dBm Transistor (HBT) IC process (MLPQ). The compact footprint, low 2 Small Footprint (3 x 3 mm ) (MOCVD). With single low voltage profile, and excellent thermal capability Low Profile (0.9mm) supply of 3.3V 20 dB power gain of the MLPQ package makes the between 2.4-2.5GHz, at a low LX5510 an ideal solution for medium- quiescent current of 65mA. gain power amplifier requirements for APPLICATIONS IEEE 802.11b/g applications IEEE 802.11b/g IMPORTANT: For the most current data, consult MICROSEMIs website: WWW.Microsemi .COM PACKAGE DATA PACKAGE DATA VCC N/C N/C VB1 VC1 VB2 N/C N/C LX5510 InGaP HBT 2.4 2.5 GHz Power Amplifier TM PRODUCTION DATA SHEET ABSOLUTE MAXIMUM RATINGS PACKAGE PIN OUT DC Supply Voltage, RF off ...............................................................................6V Collector Current ........................................................................................400mA Total Power Dissipation....................................................................................2W 13 14 15 16 RF Input Power...........................................................................................15dBm 12 VC2 1 N/C * Operation Ambient Temperature ...................................................-40C to +85C 2 11 RF IN RF OUT 1 Storage Temperature....................................................................-65C to +150C 3 RF OUT RF IN 0 Peak Package Solder Reflow Temp.

This pin is DC-shorted to GND but AC-coupled to the transistor base of the first stage. VB1 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 VB2 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, VCC resulting in a single supply voltage (referred to as Vc). RF OUT RF output. Power supply for first stage amplifier. The VC1 feedline should be terminated with a 3.3 pF bypass capacitor, VC1 followed by a 8.2 nH blocking inductor at the supply side. Power supply for second stage amplifier. The VC2 feedline should be driven with a 8.2 nH AC blocking inductor VC2 and 1 uF bypass capacitor. The center metal base of the MLP package provides both DC and RF ground as well as heat sink for the power GND amplifier.
