NDR584: 3U open vpx wideband microwave transceiver


Phase Coherent Multichannel Wideband Digital Tuner

The NDR584 is a wideband, 4-channel, 3U VPX microwave tuner that provides frequency coverage from 20 MHz to 18 GHz. The NDR584’s industry leading channel density minimizes system level SWaP. Each of the 4 channels provides a 1 GHz analog IF output with a 500 MHz instantaneous bandwidth. The channels can tune both independently and phase coherently and multiple NDR584 units can be combined for phase coherent operation. The NDR584 incorporates a super-heterodyne RF conversion architecture to minimize spurious products and yield high dynamic range performance. The fully integrated synthesizers provide fast tuning, low phase noise and the tuning flexibility to choose an alternative IF output center frequency (an IF different than 1 GHz) if desired. The NDR584 includes an internal 100 MHz OCXO and accepts both a 10 MHz reference input and a 1PPS input.
