Activity Detection Unit Technical Datasheet DG009-M1 Activity Detection Unit The DG009-M1 from Teledyne Defence Limited (TDL), is an ultra fast activity detection unit (ADU), that provides an indication of RF signal presence across the full 2.0 to 6.0GHz frequency range. The DG009-M1 consists of a power divider followed by two banks of 8 channel multiplexers, one on each arm of the power divider. The outputs from these multiplexers are terminated in diode detectors followed by high-speed video comparators providing 16 TTL digital outputs indicating the RF channel with a valid signal. Each channel of the DG009-M1 has a separately digitally programmable threshold of 32 levels over a 16 dB window. This is valid for each of the two selectable video bandwidths (10 MHz or 5MHz). The DG009-M1 has been designed such, that when RF signals are present in the crossover regions of the mulitplexers, only one FEATURES • • • • • • 2.0 to 6.0GHz Coverage 16 Channels 250 MHz Channel Bandwidths Selectable video detection bandwidths Ultra Low False Alarm rate 50ns RF pulse width capability of the two adjacent digital channels will trigger, ensuring clear and unambiguous indication of input frequency. The DG009-M1 is ideally suited to airborne transport environments of –20 degC to +80 degC and up to 50,000 feet altitude. The ADU has an ultra low false alarm rate, providing exceptionally high system reliability and probability of detection when incorporated into typical Electronic Support Measures (ESM) suites.
