8 TO 12 GHz SINGLE-SIDEBAND UPCONVERTER
MODEL: SSM0812(*)C2MD(**)
MODULATOR PRODUCTS
FEATURES
• RF output/carrier input .......... 8 to 12 GHz
• Modulation bandwidth ........... DC to 500 MHz (Q)
• Linear RF input ....................... Up to +5 dBm
• IF input power......................... +10 to +13 dBm
• Sideband suppression ........... 25 dB
• Carrier rejection...................... 35 dB
• IF options:
Single sideband ...................... A, B and C
(internal hybrid)
Multioctave IFs ....................... Q (separate inputs)
All modulators and SSB upconverters require that at least one of the input frequency bands (carrier or IF) has suf-
ficient power to turn on the semiconductors. This model employs IF drive. SSB upconverters employ an internal IF
90° hybrid to yield only one RF sideband output. This is offset above or below the input LO by the IF frequency
(test data is recorded for the upper sideband only). Schottky diode (standard) upconverters have the greatest
speed and bandwidths, but yield RF output powers of typically less than 0 dBm. PIN diode (optional) designs can
only be driven at modulation rates of less than 30 MHz, but will yield output RF powers exceeding +5 dBm. This IF
driven unit is used when the RF input has a wide dynamic range, such as for military and commercial Doppler fre-
quency or phase-shift generation. If desired, higher rejection of the undesired sideband is possible with the SME
model series.

GENERAL NOTES
1. Insertion loss relative to 0 dBm RF input. All other outputs,
including fo, are relative to the desired upper (fo + fm) output.
2. Standard SSB units with IF hybrids are aligned for upper
sideband operation. For lower sideband or selectable sideband,
contact MITEQ.
