LX5561 ® TM InGaAs – E-Mode pHEMT Low Noise Amplifier P RODUCTION D ATA S HEET The LX5561 is a low noise amplifier (LNA) for WLAN applications in the 2.4-2.5 GHz frequency range. This LNA is manufactured with an InGaAs Enhancement mode pseudomorphic HEMT (E-pHEMT) process. It operates with a single positive voltage supply of 3.3V, with noise figure of 1.5dB while maintaining input third order intercept point(IIP3) of up to +6.5dBm. The LNA is implemented with bias circuit and input/output matching circuit on chip, resulting in simple external circuit on board. In addition, the onchip bias circuit provides stable performance of gain, NF and current for voltage variation compared to a general resistor-network bias circuit. The LX5561 is available in a 12-pin 2mm x 2mm micro-lead package (MLPQ-12L).
