Millimeter Wave Multipliers (54000 Series plus Option 18)
External multipliers can be added to the MG3690A to provide
coverage as high as 110 GHz. Please call us for solutions beyond
110 GHz.
The 54000 series multipliers provide 50 to 75 GHz coverage in
WR15 or 75 to 110 GHz in WR10. An MG3690A with Option 18,
mmW bias, is required to drive these multipliers. The MG3692A
provides the input frequencies which are below 20 GHz. Higher
frequency MG3690A models could be used, but are not necessary.
Option 18 adds a rear panel BNC Twinax connector that supplies
the proper DC bias to power these external multipliers. (Option 18
is not available with Option 7.)
The 54000 series multipliers come in two versions, –4 and –5. Both
versions include input and output isolators for improved source
match. An external full-band “Through” (FL1) can be replaced with
either one of two split-band supplied external filters (FL2, FL3) for
better than –50 dBc spurious. The –5 version adds an internal
output coupler and a detector to supply a detected voltage output.
This output can be routed to the synthesizer’s external ALC input
for a flatter response, using External ALC Leveling mode.
Modulation can be used up to 110 GHz with these multipliers.
FM/ΦM’s deviation will be multiplied based on the multiplication
factor of the 54000 used. Pulse Modulation is available, with
sharper rise and fall times. AM is not recommended.
All performance is typical.
