Model QM54A10 Octave Band IQ Single Sideband ModulatorModel QM54A10 is an octave band I Q single sideband modulator that covers the frequency range of 200-400 Mhz. Is housed in a small housing using SMA female connectors. It features excellent loss of 9.0 dB, carrier and sideband rejection is 22 dBc. Isolation is greater than 40 dB, amplitude balance is less than 0.6 db and phase balance ±6 degree when is used as a demodulator.

Modulation and demodulation I Q frequency is DC-100 MHz
