An apparatus providing a direct chip to waveguide transition, comprising: one or more waveguides, a chip partially embedding each of the waveguides at a transition area positioned at a narrow side of each waveguide, and a transmitting element disposed at each of the transition areas, thereby providing one or more simultaneous, direct transitions between the chip and the waveguides.

Multiple waveguides embedded around the periphery of a chip to provide simultaneous direct transitions between the chip and the multiple waveguides

Direct chip to waveguide transition including ring shaped antennas disposed in a thinned periphery of the chip

A frequency quadrupler comprises a balanced topology which increases broadband odd harmonic suppression. The frequency quadrupler is constructed in a cascode configuration which is a two-stage amplifier composed of a transconductance amplifier followed by a current buffer. The cascode is constructed with common emitter (CE) and common base (CB) stages which further improves the multiplier frequency response. The cascode configuration enables a notch filter to be placed between the common emitter and common base stages to reduce 2harmonic generation and thereby increase 4harmonic output power, generation efficiency and conversion gain. To cancel 4harmonic components at the input that may destructively interfere with the output signal, capacitors are placed at the input of the common emitter stage, which in conjunction with the parasitic base wire inductance, form a notch filter to short the 4harmonic.

A method and system for design and modeling of transmission lines are provided. The method includes providing a set of models of core structures () of transmission line cells and expanding each of the models of core structures () to include different neighboring elements. The parameter characteristics of the expanded core structures (-) are compared to determine a model having a minimal sufficiently closed neighborhood environment. A closed neighborhood environment complies with design rules to ensure desired transmission line behavior in a real design environment. A model having a closed neighborhood environment can be used as a stand-alone model of the core structure describing the transmission line behavior in the actual design environment.

Power detector integrally formed within a printed transmission line to capacitively couple a portion of signal power propagating on the printed transmission line and a power detector circuit that receives coupled power output from the power detector to detect a power level of the signal power. The power detector is designed such that capacitance of the coupling capacitor is absorbed into a distributed capacitance of the transmission line to maintain continuity of a characteristic impedance of the transmission line.
