Abstract: A methodology is provided for processing carriers in a wireless application whereby the outputs of a multiplicity of modulated RF signal sources are combined into a single RF signal stream, that single RF signal stream being thereafter divided among the inputs of another multiplicity of RF power amplifiers. The outputs of that multiplicity of RF power amplifiers are then recombined, filtered and provided as an input to a transmission antenna.

Abstract: Apparatus for detecting the presence of a speed detection system includes a microcontroller, a laser detector circuit coupled to the microcontroller, a radar detector circuit coupled to the microcontroller and a display coupled to the microcontroller, wherein the microcontroller receives signals from the laser detector and radar detector circuits and in response to the signals fed thereto, the microcontroller provides an output signal indicating which of the laser and radar detector circuits fed a signal thereto.

Abstract: A waveguide hybrid coupler having a pair of intersecting, rectangular, waveguides formed in a planar block of material. The coupling region at the intersection of such waveguides has two pairs of opposed corners wherein at least one pair of opposed corners projects into the coupling region.Additionally, a commutating hybrid is formed by connecting two such crossguide hybrid couplers with a pair of rectangular waveguide sections of unequal length. The commutating hybrids are then further connected in cascade to form a channel branching network which will combine and/or separate a plurality of frequency channels presented to the network.
