Quadrature Demodulators (QD/Passive, AD/Active)

Quadrature demodulators directly convert RF signals to I and Q baseband outputs. Internally matched lowpass filters provide anti-aliasing for easy interfacing with digitizers or ADCs.

AD series demodulators are active designs with the best overall performance.

QD series demodulators use passive mixers for the lowest possible output noise.

The Quadrature Demodulator product line is available in the following frequencies (GHz):
0.1 – 0.5 • 0.5 – 4.0 • 0.55-1.1 • 0.6 – 2.2 • 1.2 – 1.4 • 1.2 – 2.0 • 1.4 – 2.2 • 2.0 – 4.0 • 2.0 – 6.0 • 2.3 – 2.6 • 3.0 – 4.0 • 4.0 – 7.0 • 4.0 – 8.0 • 6.0 – 10.0 • 9.0 – 12.0 • 11.0 – 14.0 • 15.5 – 18.0
