API Technologies produces a wide range of Digital Frequency Discriminators (DFDs) and Instantaneous Frequency Measurement receivers (IFMs) tailored to the stringent requirements of today’s state-of-the-art EW receivers.
API’s DFDs are available in a wide range of designs offering coverage of either specific frequency bands or full 2-18 GHz coverage in a single unit. DFDs find applications in both low cost radar warning receivers, enhancing the identification of threat signals against dense non threat background signals, and sophisticated ESM and ECM receivers, where high probability of intercept and high resolution are required enabling pulse by pulse signal de-interleaving.
Our high speed IFMs utilize either discrimination, channelization or a combination of those two techniques. API’s proprietary Suspended Substrate Stripline (SSS) technology is used, together with custom Application Specific Integrated Circuit (ASIC) processing circuits, to ensure our customers of high reproducibility, small size and low cost.
