DESCRIPTION
The NE33200 is a Hetero-Junction FET chip that utilizes the
junction between Si-doped AlGaAs and undoped InGaAs to
create a two-dimensional electron gas layer with very high
electron mobility. Its excellent low noise figure and high
associated gain make it suitable for commercial and industrial
applications.
NEC's stringent quality assurance and test procedures as-
sure the highest reliability and performance.
