The NE850R599A is a medium power GaAs MESFET designed for up to a 1/2W output stage or as a driver for higher power devices. The device has no internal matching and can be used at frequencies from UHF to 8.5 GHZ. Equivalent performance in a chip package can be obtained by using only 1 cell of the NE8500100 chip. The chips used in this series offer superior reliability and consistent performance for which NEC microwave semiconductors are known.
