Millimeter Wave Multipliers1 - 63850 series
(Option 18 recommended for DC bias.)
63850 series external, waveguide output, multipliers are available for banded frequency
coverage up to 325 GHz.
These external multipliers require at a minimum an MG3692B, with 20 GHz coverage.
The output power required to drive the modules is +10 dBm. They can be powered up
by an external power supply (+12Vdc, 1.5A typ.) using the supplied double banana
power cord. It is recommended to purchase an MG3690B with option 18, which adds the
capability to bias these modules without the need of an additional power supply. It adds
a rear panel Twinax connector that supplies the proper DC bias for these modules, and a
cable to power them up. Option 18 is not available with options 7 and 15.
63850 series multipliers have a saturated, unleveled, output power, yet their inherent
flatness is exceptional. Modulating the input drive will indeed modulate the output,
except for the case of Amplitude Modulation. Since the output is saturated, Amplitude
Modulation is not recommended with these mmW modules. Frequency and Phase
Modulation is possible, but the achieved deviation will be multiplied based on the
multiplication factor of the module. Pulse modulation is also possible, with even sharper
rise and fall times than the input. All modulation performances are not specified.
For ease of operation, the MG3690B allows the user to enter a frequency scaling factor,
the module's multiplication factor, which will be used only for purposes of displaying the
proper frequency at the output of the mmW module, on the MG3690B's front panel display.
