In this paper a MMIC design technique, oriented to the optimization of the production yields, is illustrated together with the obtained results. This method, based on a sensitivity analysis, i.e. on the circuit behavior for variations of passive elements from their nominal value, and on the contemporary determination of the production yields, allows the identification the circuit elements to ob...

In this paper, to substitute the existing TWTA(Travailing Wave Tube Amplifier) component in small radar system, we developed Ku band SSPA(Solid-State Power based on fabrication of power MMIC (Monolithic Microwave Integrated Circuit) chips. For development 500 W SSPA, 40 W-grade was designed by ADS(Advanced Design System) at Keysight company with UMS GH015 library, and processed foundry service....

This letter presents a 140-GHz frequency-modulated continuous-wave (FMCW) radar sensor for automotive applications. The monolithic microwave integrated circuit (MMIC) inside of the features one transmit (TX) and receive (RX) channel as well possibility to apply binary phase shift keying (BPSK) modulation transmitted signal. chip is bonded on printed board (PCB) that substrate waveguides (SIWs) ...

Millimeter wave radars have been developed and marketed for the purpose of reduction in deaths in traffic accidents and traffic congestion. However, the millimeter wave radars need to be cheaper to be used more widely. In order to make the radars cheaper, we developed a new MMIC (Monolithic Microwave IC) structure and bonding technology, focusing on reducing costs of RF-modules. This article de...

Motivated by recent advances in wideband-gap (WBG) gallium nitride (GaN) semiconductor technology, there is considerable interest in developing efficient solidstate power amplifiers (SSPAs) as an alternative to the traveling-wave tube amplifier (TWTA) for space applications. This article documents the general architecture considerations pertinent to developing SSPA architectures that can enable...

Backside via self-inductance is a critical electrical quantity needed for the design of Monolithic Millimeter-wave Integrated Circuits (MMIC). We have investigated a simple, analytical method for accurately calculating via inductance based upon physical geometry. The analytical method enables backside via process development to be tailored to meet design goals. Conversely, the sensitivity of RF...

The design of Microwave and Millimeter-wave Monolithic Integrated Circuits (MMIC) requires a meaningful and accurate characterization of the electron device along with information about the changes caused by the process parameter variations. Meanwhile, increasing application of multi-port GaAs FETs, adopted for side-biasing in the higher level of MMIC integration, has led to increased research ...

A methodology for guiding process-driven manufacturing organizations in instituting process control on a facility-wide basis is proposed. The methodology begins with a definition of the customer’s expectations and of the manufacturing process used to meet these expectations. The output, of a given process or subprocess must reach four progressive levels of control. When the output can be reliab...
