A series of limiters have been developed for power levels up to 58 dBm in a standard 0.25-μm BiCMOS process. After a thorough analysis of general design tradeoffs, a figure-of-merit (FOM) for limiter technologies is introduced. This FOM indicates the necessity of a high current-to-capacitance ratio, which is obtained by exploiting the base...

The trends and needs in the development of technologies like antennas and microwave circuits have clearly indicated a constantly increasing level of complexity of these structures, as well as the need of efficient and accurate analysis and synthesis tools. Such tools should provide an efficient yet accurate design approach, avoiding or...

The Military Scenario Definition Language (MSDL) and Coalition Battle Management Language (C-BML) have been proposed as new SISO standards to improve interoperability and achieve coherent behavior between C4I and simulation systems. The authors participate in a research program sponsored by the Joint Dutch Armed Forces, which studies multi...

A set of X-band absorptive limiter GaAs MMICs has been designed and realised using both the PPH25x foundry process from UMS and the PP50-10 process from WIN semiconductors. The innovative limiter concepts have been extensively characterised by both pulsed and CW measurements. Both passive and active topologies have been implemented. The passive...

This paper discusses the final result of development effort leading to a fully-integrated phased-array core chip. The MMIC is especially useful for active electronically-steered arrays, and integrates a full functionality including low-noise amplifier (LNA), a medium-power amplifier (MPA) matched to common high-power amplifiers (HPA) and all...
