APPLICATIONS/BENEFITS
The LX5503E is a power amplifier optimized for high-efficiency lowpower applications in the FCC Unlicensed National Information Infrastructure (U-NII) band, Europe HyperLAN2, and Japan WLAN in the 4.9-5.85GHz frequency range. 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). It operates at a single supply of 3.3V with +26dBm of P1dB, and power gain of 21dB between 4.9-5.35GHz and 16dB up to 5.85GHz.
For +18dBm OFDM output power (64QAM, 54Mbps), the PA provides a very low EVM (Error Vector Magnitude) of 3%, and consumes 150mA total DC current. The LX5503E is available in a 16pin 3x3mm2 micro-lead package (MLP). The compact footprint, low profile, and excellent thermal capability of the micro-lead package make the LX5503E an ideal solution for broadband, medium-gain power amplifier requirements for IEEE 802.11a, and HiperLAN2 portable WLAN applications.

Bias current control voltage for the second stage. The VB2 pin can be connected with VB1 into a single reference voltage (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. This pin is AC-coupled and does not require a DC-blocking capacitor. Power supply for first stage amplifier. The VC1 feedline should be terminated with a 220pF bypass capacitor as close to the device as possible, followed by a 1F bypass capacitor at the supply side. This pin can be combined with VC2 and VCC pins, resulting in a single supply voltage (Vc). Power supply for second stage amplifier. The VC2 feedline should be terminated with a 220pF bypass capacitor as close to the device as possible, followed by a 1F bypass capacitor at the supply side. This pin can be combined with VC1 and VCC, resulting in a single supply voltage (Vc). The center metal base of the MLPQ package provides both DC/RF ground as well as heat sink for the power amplifier.
