Design Distributed MMIC Amplifiers
The types of passive elements and their positioning in a circuit layout can greatly impact the performance of versatile distributed RF/microwave amplifiers.
Design MMICs On A Budget
Computer-aided-engineering (CAE) tools can be pricey, but it is still possible to design a low-noise amplifier at a commercial foundry using low-cost, open-source software simulators.
Designing MMIC Distributed Amplifiers
Fabricating a classic broadband amplifier design with newer PHEMT devices should provide improved performance over the same MMIC amplifier based on older GaAs MESFET devices.
Design An MMIC LNA With GaAs PHEMTs
This approach evaluates both enhancement-mode and depletion-mode GaAs PHEMTs for the design of an X-band (about 8 GHz) LNA designed to run on battery power.
Convert Distributed MICs To MMICs
Proven passive MIC components can be redesigned as MMICs with equivalent electrical performance, although at a fraction of the size and weight of their MIC counterparts.
