Model SA-69-BD is a Universal Coherent Modulator Sub-Assembly that operates from 2-18 GHz that is used in PDOA, ADOA or TDOA applications. It combines amplification and gain equalization stages, a digitally controlled vector modulator and attenuator, pulse modulator and a switched-filter bank to provide modulated signals with high-resolution amplitude and phase accuracy. It achieves 360 degrees of phase shift, 120 dB of attenuation and 80 dB of pulse modulation. It’s available in optimized bandwidths from 400 MHz to 24 GHz.
