Quadrature Modulators (QM/Passive, AM/Active)

Quadrature modulators generate any bandpass RF modulation including QPSK, QAM, OFDM, FM, PM, AM, and pulsed Doppler. I and Q baseband inputs directly modulate the LO input to generate a modulated RF output.

AM series modulators use active designs with superior linearity and have integrated LO amplifiers. QM series modulators are passive for the lowest output noise. Most products can be offered with single-ended inputs instead of differential. Please ask for details regarding the product of interest.

The Quadrature Modulater line is available in the following frequencies (GHz):
0.3 – 5.0 • 0.55 – 1.1 • 0.6 – 2.2 • 1.2 – 1.4 • 1.2 – 2.0 • 1.4 – 2.2 • 2.0 – 4.0 • 2.3 – 2.6 • 3.0 – 4.0 • 3.5 – 7.0 • 4.0 – 8.0 • 7.0 – 10.0 • 9.0 – 12.0 • 11.0 – 14.0 • 15.0 – 17.5
