A 120-W -Band Spatially Combined Solid-State Amplifier
In this paper, we present new results in the development of a broad-band spatial power-combining system implemented in a standard X-band waveguide environment. Using 24 off-the-shelf GaAs monolithic-microwave integrated-circuit (MMIC) power amplifiers integrated with tapered-slot antenna arrays, the new combining circuit produced up to 126-W maximum power output with a gain variation of 1.9 dB ...
متن کاملA W-band Simultaneously Matched Power and Noise Low Noise Amplifier Using CMOS 0.13µm
A complete procedure for the design of W-band low noise amplifier in MMIC technology is presented. The design is based on a simultaneously power and noise matched technique. For implementing the method, scalable bilateral transistor model parameters should be first extracted. The model is also used for transmission line utilized in the amplifier circuit. In the presented method, input/output ma...
متن کاملDesign of X Band High Power Amplifier MMIC Based on AlGaN/GaN HEMT
In this paper, we have presented an X band high power amplifier based on MMIC (Monolithic Microwave Integrated Circuit) technology for satellite remote sensing systems. We have used GaN HEMT process with 500 nm gate length technology with VD= 40 V and VG= -2 V in class E structure. The proposed two-stage power amplifier provides 25 dB power gain with maximum output power of 49.3 dBm at 10 GHz. ...
متن کاملLaser Cooled High-Power Fiber Amplifier
A theoretical model for laser cooled continuous-wave fiber amplifier is presented. The amplification process takes place in the Tm 3+ -doped core of the fluoride ZBLAN (ZrF4-BaF2LaF3-AlF3-NaF) glass fiber. The cooling process takes place in the Yb 3+ :ZBLAN fiber cladding. It is shown that for each value of the pump power and the amplified signal there is a distribution of the concentration of ...
متن کاملKa-Band Wideband-Gap Solid-State Power Amplifier: General Architecture Considerations
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...
