Multi-Channel Interpolating Up Converter

The Army is looking to design, develop, and fabricate a multi-carrier wide band digital In phase and Quadrature phase to composite analog converter. The device accepts digital data and synthesizes and analog Intermediate Frequency (IF) having an instantaneous bandwidth of 1 GHz ranging from 950 to 1950 MHz. The up conversion process must manage signal scaling, to account for adding multiple bands together while meeting spectral mask requirements. The desired performance supports 96 carriers with bandwidths ranging from 64 KSPS to 26 MSPS. Bedford Signals proposes to solve this problem by using our patent pending Arbitrary Waveform Generator (AWG) to interpolate and up convert digital data samples to a higher bandwidth. The algorithms can be verified via demonstration on our existing DSP boards, and ported to a custom DSP board for a full scale full bandwidth demonstration.
