520 | |a"A 19.2 GHz cooled low-noise amplifier was developed for a ground terminal application utilizing HEMTs and quartz substrate in a conventional microstrip format. Cooling was provided with thermoelectric devices and a 1.98 dB noise figure and 15 dB associated gain were achieved at 19.2 GHz. The noise figure over the 18.85 to 19.55 GHz frequency band was under 2.2 dB. Two approaches were implemented. Part I describes the "conventional" approach where the entire LNA module was cooled, while Part II describes the "novel" approach where only the HEMT chips were cooled"--Abstract, page iii. |
