S-band microcircuit power amplifier
Research, design, development, and fabrication of a two-stage, solid-state, microcircuit power amplifier operating in the 2.25 GHz region of the S-band are summarized. Output is typically 7.0 watts for an input of approximately 400 mw. Input stage is an MSC 3001 transistor; output stage is an MSC 3005 transistor. Input VSWR is 1.4:1.0, or less. Efficiency of 33.3 percent or more is achieved. Second and third harmonic suppression is 30 db. Operating power is 28 VDC. The entire unit has a length of 3.80 inches, a width of 2.08 inches, and a height of 1.00 inch.
