41 GHz 10 Watt Solid State Amplifier

A solid state amplifier has been developed at 41 GHz and demonstrates 10 watts of CW output power. A two stage design using silicon double drift IMPATT diodes operating in the injection locked mode exhibits an operational bandwidth of 250 MHz with an associated gain of 32 dB. Computer aided design and analysis has been used for circuit modeling and optimization. This approach was instrumental in eliminating a significant number of tuning elements typically associated with this type of amplifier. This 10 watt performance at 41 GHz represents the highest frequency, highest solid state output power achieved to date.
