TGA11135B is designed to support a variety of
millimeter wave applications including point-to-
point digital radio and LMDS/LMCS.
The balanced configuration two stage design
consists of a pair of 600um input devices driving a
4 x 600um output stage. Power combining is
achieved with on-chip Lange couplers.
