The DA4 series consists of three different modules, with input frequency ranges of 0.5 to 2 GHz, 2 to 8 GHz and 8 to 18 GHz. All the modules have an output IF range of 10 MHz to 250 MHz and deliver excellent microwave performance, with a conversion gain of 21 dB, noise figure of 8.5 dB and output power of 10 dBm. Channel-to-channel tracking is specified as +/-5 degrees for phase tracking and +/-0.5dB for amplitude tracking.
Three of the four channels can be used for a monopulse radar receiver and the fourth for spur identification. The modules are also suitable for basic direction-finding applications with four antennas and are available in an integrated package with SMA Female connectors for the inputs and outputs, measuring 88.4 x 88.4 x 19.1 mm (excluding connectors).
