Skyworks SKY671xx pHEMT Low-Noise Amplifiers are GaAs, pHEMT Low-Noise Amplifiers (LNAs) with an active bias and high linearity performance. The advanced GaAs pHEMT enhancement mode process provides excellent return loss, low noise, and high linearity performance. The internal active bias circuitry provides stable performance over temperature and process variation. The device offers the ability to externally adjust supply current and gain. Supply voltage is applied to the RFOUT/VDD pin through an RF choke inductor. The SKY67110 operates in the frequency range of 0.30 to 0.75 GHz with proper tuning. The SKY67151 operates in the frequency range of 0.7 to 3.8 GHz using a common layout and band-specific tunes.
