Product Overview
The Quad Digital Receiver (QDR) Board is a 6U conduction cooled board with VPX connector for backplane interfacing.
The board has four high speed ADCs capable of sampling RF signals synchronously. The board has FPGAs to implement signal processing algorithms.
IF front-end module with 1 GHz bandpass filter and amplifier for signal conditioning. Supports data transfer, configuration and remote upgradation of firmware over Gigabit Ethernet interface.
The board is used for RF signal acquisition and processing in electronic warfare systems.
