Customer Feedback
QuinStar’s Ka/Q/V-band SSPA has flown on the Aldo Paraboni payload aboard AlphaSat TDP5 for over 10 years of flawless on-orbit operation. Their engineering rigor and quality management gave us confidence from day one.
Giuseppe Codispoti, Italian Space Agency (ASI)We are very satisfied with QuinStar’s services for our W-band SSPA needs. Since 2015, we have had no failures across hundreds of units delivered. Their responsiveness and technical depth are unmatched.
Nicholas Tarasenko, BlueHaloWe replaced our legacy klystron transmitters with QuinStar solid-state power amplifiers. The result was dramatically improved reliability, reduced maintenance, and better overall system performance for our radar instruments.
