Rogers5880 substrate, remaining circuit use 50um quartz substrate, input waveguide 1 use waveguide WR15, output waveguide 9
Subtract wide waveguide WR5 using height is subtracted.Direct current input and filter 3 are connected into quartz substrate by the way of jumping spun gold.
V-band (40-75GHz) driving signal enters quartz substrate by input waveguide 1 and local oscillator waveguide transition 2, by this
Polarization filter 4 and input matching circuit 5 enter Schottky variable capacitance diode 6 and generate higher hamonic wave.Due to local oscillator filter 4
In the presence of, secondary or more harmonic wave can not all return to the left end of circuit, simultaneously because output subtracts the high presence for subtracting wide waveguide 9,
Second harmonic also cannot be introduced into output waveguide, cooperate both ends match circuit, and only triple-frequency harmonics can be exported from output waveguide.
Direct current input and filter 3 in DC filter main function be prevent input V-band driving signal from quartzy main circuit into
Enter Rogers5880 substrate.In order to which the processing is simple, two filters (local oscillator filter and DC filter) are all made of high Low ESR
Cable architecture.
Radio frequency transition uses the form of probe transitions, as shown in Figure 2.The radio-frequency plumbing transition 8 passes through microstrip probe defeated
Out in the paracentral hole insertion waveguide cavity of 9 width of waveguide, the probe of coupling is played the signal energy in microstrip line by one section
It is coupled in waveguide.The frequency tripling signal come out from diode is coupled in waveguide by probe, the shielding chamber size of microstrip line
By optimization, it is avoided that the appearance of waveguide mode.It is to match and enter by second harmonic that output waveguide 9, which subtracts height and subtracts width,
In waveguide.The simulation result of radio-frequency plumbing transition is as shown in figure 3, as seen from the figure in the frequency range of 160~180GHz
