Skyworks’ SKY67015-396LF is a GaAs, pHEMT, low-noise amplifier exhibiting high linearity and excellent return loss, while drawing as low as 5 mA of bias current. The internal active bias circuitry provides stable performance over temperature and process variation. The LNA offers the ability to externally adjust supply current between 5 - 20 mA. Noise Figure of 0.80 dB, 17.5 dB Gain and 25 dBm OIP3 are achievable at 0.25 GHz with 3.3 V supply and 18 ma of bias current. The device can also be biased from 1.8 V to 5 V and will still achieve an OIP3 of 16 dBm, and 12 dBm OP1dB with only 5 mA of bias current from 3.3 V supply. Target applications include ISM band and high frequency wireless metering, sensors, microphones, military and battery-powered transceivers. The amplifier is ideally suited for receiver applications requiring low NF and high linearity, and for applications requiring portable VHF and ISM band equipment. Manufactured in a compact, 2 x 2 mm, 8-pin DFN package, the SKY67015-396LF LNA operates in the frequency range of 30 to 300 MHz and the associated evaluation board is optimized for operation at 250 MHz.
