DESIGN OF A MOLECULAR AMPLIFIER GROUP
Abstract
The research objective is to design, construct, and test a molecular amplifier group for lownoise amplification in the 2150 to 2350 mc band. The requirements for this amplifier are: (1) a noise factor of less than 0.5 db, (2) a gain greater than 20 db, (3) a bandwidth of at least 4 mc, and (4) ease of tuning over the 2150 to 2350 mc band. The reactance amplifier, the electron beam parametric type amplifier, the mavar (ferromagnetic amplifier), and the solid-state maser were investigated for best system characteristics. The traveling-wave maser was selected as the receiver configuration that will best meet the requirements. Slow-wave techniques for the traveling-wave maser are discussed. Using this technique slowing factors greater than 100 can be achieved over the required bandwidth. Open and closed refrigerating systems, and tentative system packaging techniques are presented.
