Abstract: The present disclosure, for example, relates to one or more techniques for linearizing a signal in a communications system. An input signal may be obtained at a beginning of a signal path of a radio frequency (RF) communication device. The RF communication device may estimate subsequent distortion of the input signal due to the signal path. The estimated distortion may include estimated phase distortion and estimated amplitude distortion of the input signal. The RF communication device may adjust phase and amplitude within the signal path to compensate for the estimated phase distortion and the estimated amplitude distortion to produce an adjusted signal. The phase within the signal path of the input signal may be adjusted separately from the amplitude within the signal path of the input signal. The RF communication device may generate a linearized signal at an end of the signal path based at least in part on the adjusted signal.

Abstract: Systems, devices, and methods are provided for reducing noise in communication systems. An example resonator system comprises: a housing comprising a top portion and a floor portion, a dielectric resonator positioned with the housing, a substrate, and a stripline transmission line adjacent the substrate. In this exemplary embodiment, the stripline transmission line within the housing is electromagnetically coupled to the dielectric resonator, the substrate is positioned away from the floor portion and top portion of the housing, and the dielectric resonator coupled with the suspended stripline transmission line is connected to an active device to form an oscillator. The positioning of the substrate relative to the housing may reduce the amount of the electromagnetic field from the stripline transmission line that is absorbed into the housing. In a further embodiment, the board has no metallic backing on at least a portion of the back of the board.

Abstract: A power amplifier uses a plurality of solid-state amplifiers (FIGS. 2 and 3, 140) arranged in a parallel manner to form a power amplifier module (10). Each solid-state amplifier is adhered to a low thermal expansion insert (130). The insert is then coupled to a low cost aluminum substrate in order to carry the excess heat from each solid-state amplifier (140) to the aluminum housing. The power outputs from the solid-state amplifiers from each module are combined with the power outputs from other modules using electroformed waveguide combiners (FIG. 1, 30, 40).

Abstract: An antenna subsystem (120) which comprises an electronic scanning reflector antenna (400) is used for the formation of single and multiple beams. Reflecting surface (420) is covered with at least one dielectric layer (430) which is used to simultaneously and independently steer multiple beams. Electronic scanning reflector antenna (400) operates similar to a phased array antenna. ESRA (400) comprises a number of independent controllable reflecting surfaces (450) which are combined together in close proximity. Each one of the individual regions is covered by a dielectric layer, and the dielectric constant for each can be independently controlled. Electronic scanning reflector antennas (400, 600) are used in both space-based and terrestrial-based applications. Electronic scanning reflector antennas (400, 600) are used for both transmission and reception of electromagnetic signals.
