“…In the OFF-state, the lumped element equivalent circuit is a series LC (0.4 nH inductor in series with 52 fF capacitor) circuit connected in shunt to the main line. The expressions for the S 21 of the lumped circuits in the ON-and OFF-states are given by (2) and (3), respectively.…”

“…The main emphasis is to make the components more compact, and cost-effective. Non-radiative dielectric waveguide is a prominent transmission medium that can be used to develop high performance and low cost systems at millimeter-wave frequencies [1][2][3]. NRD guide consists of a rectangular dielectric strip, of cross-section a × b and relative dielectric constant ε r , which is sandwiched between two parallel metal ground plates (figure 1).…”

This paper reports the determination of electrical equivalent circuit of ON/OFF modulator in non-radiative dielectric (NRD) guide configurations at Ka-band. Schottky barrier mixer diode is used to realize this modulator and its characteristics are determined experimentally using vector network analyzer. Full wave FEM simulator HFSS is used to determine an equivalent circuit for the mounted diode and modulator in ON and OFF states. This equivalent circuit is used to qualitatively explain the experimental characteristics of modulator.

SUMMARYIn this paper, NRD-guide and waveguide H-plane transitions are proposed to propagate a millimeter wave from the dielectric strip to the upper surface of the conductor plate through a waveguide made by excavating the conductor plate. As a result, they have a bandwidth of about 4 GHz with |S 11 | ≤ -15 dB and a low transition loss of 0.2 dB in the 60-GHz band. An NRD-guide upper side dielectric lens antenna was designed and fabricated as an application of the proposed transition. It had a wide bandwidth of about 6 GHz with |S 11 | ≤ -15 dB, high efficiency of about 78%, and a low sidelobe strength of less than -27 dB.

By coupling the ceramic resonator to the dielectric strip longitudinally, an injection range of the oscillation frequency was enlarged, and therefore, the oscillation stability was more improved than the previous one.…”

Abstmd -Small sized and high performance millimetep wave source, which consists of Gunn diode mount, circulator and matched load, was developed based on the NRD guide technology at 60 GJh. Main emphasis was placed on compatibility with rectangular waveguide systems. A transition between an NRD guide and a rectangular waveguide was devised and fully optimized by using electromagnetic simulator (HFSS). Good advantages such as a medium level output power of 13 dBm, a small phase noise less than -113 dBc/Hz for 300 kB[z offset, and a small frequency stability less than -1.3 p p d C were obtained. The size is smaller than that of a name card. It is confirmed that the performance of the developed Gunn oscillator is higher than that of a commercially available rectangular waveguide type GUM oscillator from the viewpoint of the output power, phase noise, and frequency stability.Index Tenns -NRD guide, Gunn oscillator, transitions, Low phase noise, temperature coefficient.
