Schottky diode (standard) modulators have the greatest speed and bandwidths, but yield RF output powers of typically less than 0 dBm. Greater output power can be achieved by using higher level diodes with proportional increases in carrier power. Some carrier driven units are used when the modulation input to RF output must be linear (low harmonics). A typical application is for digital QPSK with cosine shaped pulses (for minimum bandwidth). Many SSB upconverters also require input-to-output signal linearity, thus requiring LO drive.

IQ Modulators:

• Carrier Driven IQ Modulators
• Modulation Driven IQ Modulators

MITEQ designs and manufactures a broad range of standard frequency modulators, which include:

• BPSK and Bi-Phase Modulators
• Double-Sideband Upconverters
• QPSK and QAM modulators.

MITEQ maintains dedicated engineering resources to modify our standard designs in support of custom-generated specifications.

All modulator products are backed by MITEQ's 3-Year Warranty and most are available as RoHs Compliant components.
