Avago Technologies
High Linearity LNAs with Fail-Safe Bypass

Avago Technologies High Linearity LNAs with Fail-Safe Bypass are easy-to-use GaAs MMIC Tower Mount Amplifier (TMA) LNA modules with a low IL bypass path. Avago Technologies High Linearity LNAs with Fail-Safe Bypass have low noise and high linearity achieved through the use of Avago Technologies' proprietary 0.25mm GaAs Enhancement-mode pHEMT process. All matching components are fully integrated within each module and the 50ohm RF input and output pins are already internally AC-coupled. This makes these LNAs extremely easy to use as the only external parts are DC supply bypass capacitors. All ALM-11x36 LNAs share the same package and pin out configuration.
