NDR504 Four-Channel Downconverter | Phase Coherent | Rugged Design

NDR504

The NDR504 is a four channel 18 to 40 GHz downconverter with IF outputs below 18 GHz. Each downconverter channel has a 2-band sub-octave preselector at the input stage covering the 18 to 26.5 GHz and 26.0 to 40 GHz frequency bands.

Most NDR products offer GNURadio modules to provide seamless open-source software development. More information can be found here.

Benefits

FLEXIBLE INSTALLATION

The NDR504 enables flexibility for installation near any antenna aperture: on the ground, on UxS, and in airborne environments. Its IF output connects to any 18 GHz receiver, making it widely deployable in new and existing systems, and compatible with a range of Epiq Solutions products for further processing.

PHASE COHERENCE ACROSS CHANNELS

The NDR504 ensures phase coherence across all four channels by distributing a single integrated local oscillator (LO) frequency, crucial for accurate multi-channel signal processing and ideal for independent search, phase coherent DF, and other combinations.
