All modulators yield a frequency spectrum that utilizes both sidebands on either side of the output suppressed carrier. SSB upconverters employ an internal IF 90 degree hybrid to yield only 1 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) modulators 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. PIN or Schottky modulators that vary only the RF carrier phase, in many discrete steps or continuously, are referred to as phase shifters or frequency translators respectively. When output RF amplitude and phase control is required, the device is usually called a vector modulator. For the latter device, phase accuracy is usually specified over a given amplitude range (in dB). All MITEQ modulators can be driven in the carrier or modulation modes as explained below, but test data is only recorded in the modulation driven mode. SECTION 3 NOTES Note 1: Carrier driven: LO = +13 dBm, I/Q = 0 dBm. Used when any amplitude variation or pulse shape of the modulation must be accurately transferred to the RF output envelope. A communication example would be directly modulating a microwave carrier with Gaussian shaped I/Q digital pulses to minimize the channel bandwidth required. Note 2: Modulation driven: RF = 0 dBm, I/Q = +10 dBm or 10 mA or TTL. Used when RF input has wide dynamic range, such as for military and commercial Doppler frequency shift generation or corrections. If desired, the harmonic distortion of the relatively fixed and higher level I/Q drive third order harmonics can be linearized by "resistance/diode" or digital "ROM" wave shaping techniques. The latter is often used in vector modulator applications, such as in the model SME0618LI1DIQ design. Note 3: To specify the IF frequency for SSB upconverter usage, select from the following standard options and add to end of model number or contact MITEQ: Suffix A: 20-40 MHz, Suffix B: 40-80 MHz, Suffix C: 100-200 MHz, Suffix D: 500-1000 MHz, Suffix Q: I/Q inputs Note 4: Conversion loss (CL) is relative to lowest power input (fo, fm). All other outputs (including fo, are relative to the desired upper (fo + fm) output. Note 5: Standard units with IF hybrids are aligned for upper sideband operation. For lower sideband or selectable sideband, contact MITEQ. Note 6: Last two characters in model number indicate standard outline number, see outline section. Note 7: Question and answer modulator application notes available, contact factory. Note 8: Hermetically sealed housing. 9
