Frequency extender modules of vector network analyzers and signal generators, as well as front-end modules of semiconductor automatic test systems, make use of broadband resistive diode frequency multipliers. This paper presents the design and fabrication of innovative planar varistor frequency multipliers. Three frequency triplers (#1, #2, #3) and two frequency doublers (#4, #5), operating in the 60-110 GHz and 50-110 GHz frequency ranges, respectively, are designed. The hybrid architecture utilizes commercial gallium arsenide Schottky diodes from United Monolithic Semiconductors on thin-film processed high-permittivity alumina substrate. Synthesis is based on a co-simulation procedure between 3-D electromagnetic field and nonlinear harmonic balance circuit simulations. Scalar and spectral measurement data over the focused output frequency ranges are presented. Conversion loss values around 18 dB from 60 to 95 GHz and below 22 dB from 60 to 110 GHz are achieved with frequency tripler #1. Frequency doubler #5 achieves conversion loss values below 15 dB from 50 to 89 GHz and below 22 dB from 50 to 110 GHz. A comprehensive comparison of the presented work with reported frequency multipliers is included.Index Terms-Hybrid multiplier, longitudinal E-field probe, 1.00-mm coaxial connector, planar -band multiplier, Schottky diode frequency multiplier, varistor doubler, varistor tripler.

“…In [18], a network-analytical method is used to explain the distributions of passbands and stopbands of the stub-loaded stripline/finline periodic structures. In [19], a simple method based on an equivalent circuit is proposed to analyze the stub-loaded microstrip periodic structures (SL-MPS), where the presented formulas reveal that the bandwidth and left-edge cutoff frequency of the first passband can be mathematically determined by the lengths of the loaded stubs. In [20], the transmission characteristics of stubloaded stripline periodic structures are analyzed and meanwhile two different structures are employed to achieve suppressions of specific modes.…”

In this paper, a grounded stub-loaded microstrip periodic structure (SL-MPS) is presented and its transmission characteristics are investigated. A new method of suppression of modes is proposed through adding grounded via holes on the grounded SL-MPS for the design of bandpass filters (BPFs). In order to validate the feasibility of suppression of modes of grounded SL-MPS, two cases of BPFs with different dimensions are designed. For the case of BPF with suppression of adjacent modes, the simulated and measured results of BPFs demonstrate that the fundamental and 2nd high-order modes can be effectively suppressed. For the other case of BPF with suppression of multiple modes, the fundamental, 1st, 3rd and 4th high-order modes can be successfully suppressed. The measurements of these BPFs are reasonably in agreement with their simulations. Observed from the theoretical analysis and experimental results, the proposed method can effectively widen the stopband of BPF by suppressing unwanted modes.
