Skyworks is introducing a series of high gain, two stage LNAs employing both GaAs PHEMT and GaAs HBT technology that offer very low noise figure, high linearity and excellent return loss in a small, quad flat, 4 mm squared leadless package. On-die, active-bias design ensures consistent performance and enables unconditional stability. The PHEMT front-end enables ultra low noise figure, while the HBT-based output stage provides customers a compelling solution with both high linearity and efficiency.
The SKY67105-306LF (0.6 to 1.1 GHz) and the SKY67106-306LF (1.5 to 3 GHz) high gain, low noise amplifiers are well suited for cellular infrastructure applications such as tower mounted amplifiers, remote radio units, repeaters and base stations. These new LNAs also enable traditional wireless infrastructure OEMS and broad market wireless OEMs that provide small cost sensitive receivers to offer very low noise amplification (< 0.75 dB noise figure), high linearity (+38 dBm OIP3), and higher gain (> 32 dB) than typically provided by a single stage LNA solution.
