Design and fabrication techniques for lumped-element circuits at microwave frequencies. A1.0-Gc, two-stage transistor amplifier illustrates the design procedure. Thin films and bonded transistor chips are used.
Gridded triodes are proven practical for amplifiers to 5 Gc and for oscillators to 10 Gc. Here are the best ways of selecting and using these tubes.
All factors that affect beam-pointing accuracy are evaluated; formulas are developed for quantitative determinations.
Detailed system analysis shows merit for both approaches. The authors also examine a hybrid system combining the best features of lasers and microwaves.
“Pilot” satellite would carry 24 transponders. Up to 36 ground antennas involved.
This design produced a small uhf cavity-backed slot antenna with over 5-Mc bandwidth, 10-W power rating and a VSWR less than 2:1.
Weight, space and dollars are saved by combined fabrication of radome and antenna as a single unit. Slotted-waveguide antennas are particularly suitable for such “Radant” systems.
