LX5560 TM ® InGaAs – E-Mode pHEMT Low Noise Amplifier P RODUCTION D ATA S HEET DESCRIPTION KEY FEATURES 0.5µm InGaAs E-mode pHEMT 4.9 - 6GHz Operation Single 3.3V Supply Gain ~ 12dB Noise Figure ~ 1.7dB Input IP3 ~ +6dBm Input P1dB ~ +2dBm On-Chip Bias Circuit On-Chip Input Match Simple Output Match 2x2mm² MLPQ 12 Pin Low Profile 0.5mm APPLICATIONS The LX5560 is a low noise amplifier (LNA) for WLAN applications in the 4.9-6.0 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(NF) of 1.7dB while maintaining input third order intercept point(IIP3) of up to +6dBm. The LNA is implemented with bias circuit and input matching circuit on chip, resulting in simple external circuit. In addition, the on-chip bias circuit provides stable performance of gain, NF and current for voltage variation compared to a general resistor-network bias circuit. The LX5560 is available in a 12-pin 2mmx2mm micro-lead package(MLPQ12L). W WW . Microsemi .
