Cross-coupled GaAs MESFET-based circuits for potential MMIC applications

GaAs MMIC design techniques and technology can only be accepted if adequate circuit performance is obtained, including wide bandwidth and good linearity. It is shown that the cross-coupled MESFET pair can be viewed in a rather general way with the advantage that it facilitates implementation of a whole range of interesting linear circuit building blocks, potentially useful for MMIC applications, including linearized amplifiers, signal splitters, signal combiners, circulators and tunable filters.<>
