[ 1 ] - Design 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. ...
[ 2 ] - First mesospheric in-situ measurement in Iran using sounding rockets and plasma impedance probe (PIP)
This paper reports on the progress for the first development of rocket probe for in-situ measurement of ionospheric plasma parameters in Iran. The designed probe known as Plasma Impedance Probe (PIP) will be used to measure the electron density, electron-neutral collision frequency, background magnetic field, and temperature in the mesospheric and in the altitude range of 70 km to 150 km. This ...
