Anritsu MG3690A manual mmW Frequency Coverage

mmW Frequency Coverage

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.MG3690A with 54000 Series Millimeter Wave Multiplier 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/Φ M’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.
