NDR562: Wideband Microwave Digital Tuner

 

The NDR562 wideband digital tuner is a super-heterodyne downconverter that covers RF and Microwave signals from 20 MHz to18 GHz. The tuner has a 1 GHz analog IF output with selectable bandwidths of 500 MHz, 320 MHz and 200 MHz. An integrated high dynamic range 14-bit Analog-to-Digital converter (ADC) is utilized to digitize a 500 MHz wide IF at a 1344 Msps sample rate. An onboard Kintex UltraScale series FPGA is used for the channelizer, the VITA-49 formatter, data multiplexer and the 40 Gigabit Ethernet Digital IF data interface. The Digital IF output supports bandwidths of 80 MHz, 100 MHz, 160 MHz, 250 MHz, 320 MHz and 500 MHz. An internal ARM A8 microprocessor running embedded LINUX is used for command/control of the unit via an Ethernet interface and power is derived from a 115 VAC external power supply input (power consumption is 100 Watts). The unit is housed in a 1U, 19 inch equipment frame with 19"x18"x1.7" overall dimensions that provides RF shielding, thermal management, and protection suitable for harsh environments.
