Single Sideband Modulator: PSM-50M1G-CD-1

April 12, 2012

PSM-50M1G-CD-1PMI Model PSM-50M1G-CD-1 is a single sideband modulator that operates over the 50 MHz to 1.0 GHz frequency range. The input P1dB is +5 dBm typical and has an IF Modulation Range of DC to 10 MHz. The IF Modulation Power Range is +7 dBm minimum and +13 dBm maximum into 50 ohms.

The conversion loss is 10 dB maximum and this model provides carrier suppression of 20 dBc typically. The Quadrature Phase Accuracy is ±10 degrees maximum with a Quadrature Amplitude Accuracy of ±2.0 dB maximum. This model is supplied in a package measuring 6.0" L x 3.5" W x 1.0" H.
