MGA-14516

MGA-14516 High Gain, High Linearity Active Bias Low Noise Amplifier Data Sheet Description Avago Technologies’ MGA-14516 is a two stage, easy-touse GaAs MMIC Low Noise Amplifier (LNA) with active bias. The LNA has low noise with good input return loss and high linearity achieved through the use of Avago Technologies’ proprietary 0.5um and 0.25um GaAs Enhancement-mode pHEMT process. Both LNAs have an extra feature inside that allows a designer to adjust supply current. The first stage has an additional feature where the gain can be adjusted externally without affecting noise figure. Minimum matching needed for input, output and the inter-stage between the two LNA. It is designed for optimum use between 1.4GHz to 2.7GHz. For optimum performance at lower frequency from 400MHz to 1.5GHz, the MGA-13516 is recommended. Both MGA-13516 & MGA-14516 share the same package and pinout.
