Planar D-band frequency doubler and Y-band tripler on PTFE laminates

Abstract

To extend the frequency range of existing short-range radar modules for industrial applications, millimeter-wave frequency multipliers based on cost-effective PCB technology are required. This paper describes a zero-bias D-band frequency doubler and Y -band frequency tripler based on pure PTFE material and the commercially available DBES105a diode from United Monolithic Semiconductors (UMS). At an input drive level range of 16 dBm to 18 dBm the multipliers deliver output power levels POUT E [5, -5] dBm from 100 GHz to 160 GHz and POUT E [-11, -20] dBm from 180 GHz to 230 GHz.

Design and Fabrication of Broadband Hybrid GaAs Schottky Diode Frequency Multipliers

“…Without the use of parallelization algorithms, such a 3-D EM simulation takes less than two hours using an ordinary personal computer. The authors have successfully applied similar co-simulation approaches to synthesize broadband planar multipliers [3]- [5], mixers [6], [7], and detectors [8].…”

“…The dimensions of the DGS are fixed, and two linear tapers allow for adjusting the operating frequency of the backshort. The authors have successfully applied a similar approach to build D-band frequency doublers [5] on PTFE with 50-m thickness and WR12 input and WR6 output waveguide. The length of the finline ( 1850 m) is chosen to achieve sufficient fundamental rejection (43 dB at 35 GHz) and to reduce reflections of the finline taper from 180 to 30 m. At the output, the uFIN to MSL transition from x3_uFIN (Section V) is used.…”
