Variable power dividers (VPD'S) are used for electronically despinning an antenna on a rotating satellite, and for beam steering or shaping in a multiple-beam satellite antenna system. Designs of each type for the SMS and DSCS III satellites are desc

The basic QPSK modulator of the 1970-75 era in worldwide telecomnunications has yielded new modulation techniques of BPSK, SQPSK, 8-QPSK, and FFSK which use the basic PSK device technologies. The PSK modulators must today, meet many new requirements

The general usage of multibeam antennas in satellite communication system is reviewed, and design constraints for a six-beam reconfigurable satellite antenna system are considered. These show that losses in the variable beam-forming network (BFN) Iim

Future communication satellites will require multiple reconfigurable antenna beams to achieve competitiveness and adaptability in the international marketplace. A preferred method for achieving this is by multibeam active arrays, using separate contr

A theoretical analysis of a four-frequency parametric-diode up-converter is presented, retaining both sum and difference frequencies generated by mixing of pump and signal. Upper and lower sideband up-converters are compared, and it is shown that the
