AL34 0.5 dB 1.5-2.6GHz Low Noise Amplifier

Sanland’s AL34 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA). The LNA has low noise and high linearity achieved through the use of 0.5um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 2.0 x 2.0 x 0.75mm3 8-pin Quad-Flat-Non-Lead (QFN) package. It is designed for optimum use from 1.5GHz up to 2.6GHz. The compact footprint and low profile coupled with low noise, high gain and high linearity make the AL34 an ideal choice as a low noise amplifier for cellular infrastructure for GSM and CDMA.
