PLT03-500L

General information

Designed for band III amplification as final and driver stage, it includes only one device capable of 50W RF output. The RF module is provided of the simple processing to satisfy all typical controls necessary for driver application in the high power amplification chain, by processing and managing the signals of Power input , Power gain adjustment, Phase in/out adjustment, RF switch-off.
