    Demand for in-orbit capacity through the use of satellite systems will continue throughout the next two decades. The potential of the 30/20 GHz frequency band for fixed satellite services will be exploited. However, many technology questions must be answered if the band is to be used commercially because of the high rain fades that can occur at these high frequencies. NASA has conducted a technolo...

    A design procedure for 30/20 GHz trunking systems is presented which permits the joint optimization of the satellite links and the terrestrial links between diversity terminals of individual earth stations. This process involves the generation of uplink and downlink power control functions (PCF's), which depend on 1) the rapidity with which power control can be exercised, relative to the rate of v...

    GaAs FET amplifier modules for 20 GHz band satellite communications have been developed using newly developed power FETs. The deep recess gate structure was adopted in the power FET, which improved both power output capability and power gain. Power added efficiency of 22 percent with more than 1 W power output has been achieved with 3 mm gate width FETs. The amplifier modules containing two-stage ... View full abstract»

    Under severe rain conditions there may be significant amounts of multiply-scattered millimeter wave radiation present in the vicinity of the receiving antenna for a satellite downlink. This paper explores angle diversity reception of the scattered radiation as an alternative to spatial (multiple site) diversity for ameliorating rain attenuation. Results from scalar plane-wave transport theory for ... View full abstract»

    The radio local distribution system (RLDS) has been proposed to transmit various business information signals. The proposed RLDS uses a 26 GHz band and time division multiple access (TDMA). The main features of the RLDS are the use of radio equipment containing the microwave integrated circuit (MIC) and the adoption of the demand-assigned TDMA (DA/TDMA) technique. The MIC is more suitable than con... View full abstract»

    Millimeter wave antenna technology has had a long history of development, and as millimeter wave systems evolve through planning to implementation, a significant amount of additional development work will be required. Millimeter wave antennas play a key role in the rationale for millimeter system designs because high spatial resolution can be achieved with modest physical dimensions. Reflector, le...

    Rain outage performance on route diversity systems, necessary for the circuit design of millimeter communication systems, is examined by comparing it to that of a tandem system. The analysis is mainly based on the attenuation data measured over about two and a half years at the 20 GHz band on 13 tandem links near Tokyo. It is shown that the joint probability of rain attenuation on two paths can be... View full abstract»

    Propagation tests were conducted on the 23 GHz and 40 GHz bands on the same 1.08 km path in Nagoya City, Japan, for two years (1979 and 1980), in order to collect circuit design data for a highly reliable millimeter wave intracity communication link. The path attenuation versus 1 min rain rate relation for the same cumulative percentage of time was obtained and compared to the theoretical curves o... View full abstract»

    Advantages and drawbacks of using millimeter waves in the telephone and data subscriber distribution network are listed. Fields in which it seems attractive to use millimeter wave loops are examined. For such applications, cost and reliability constraints led to the design of very simple systems. Two systems will soon be introduced into the French subscriber plant. The first one will be commission... View full abstract»
