An advantage of the new system is the increased level of wheel speed control afforded by the 3-phase control cycle, which now operates at 18 MHz ( up from 12 MHz ) and has increased ROM capacity ( 32kB up from 12kB ).

The low cost per unit, combined with its unique characteristic, have warranted its use in a wide variety of applications like oscillators, pulse generators, saw-tooth generators, triggering circuits, phase control, timing circuits, and voltage-or current-regulated supplies.

Polarization modulated ENDOR ( PM-ENDOR ) uses two perpendicular rf fields with similar phase control units to CP-ENDOR . However, a linearly polarized rf field which rotates in the xy-plane at a frequency less than the modulation frequency of the rf carrier is used.

This forces the transmitted beam to be centered precisely on the rectenna and to have a high degree of phase uniformity; if the pilot beam is lost for any reason ( if the transmitting antenna is turned away from the rectenna, for example ) the phase control value fails and the microwave power beam is automatically defocused.

Homes could be ( have been ) supplied by DC mains but AC distribution is universally preferred because of its advantages of low-cost voltage conversion by transformers, the possibility to balance generators and loads in a network by phase control, and other minor advantages in avoiding corrosion at connections between dissimilar metals, arc quenching and avoiding permanent magnetization.

The Radar consists of a surveillance antenna array with 4000 phase control modules ( PCM's ) operating in the G / H-Band ( 4-8 GHz ), engagement antenna array with 1000 PCM's operating in the I / J-Band ( 8-20 GHz ), a 16-element IFF array and steering units.
