Direct SAMpling Digital ReceivER (DISARMER)
Abstract
The goal of the Direct SAMpling Digital ReceivER (DISARMER) program is to produce a hybrid photonic-electronic analog-to-digital converter (ADC) capable of coherently sampling the entire X-band (8-12 GigaHertz (GHz)). Conventional electronic wideband receivers are limited in dynamic range by both the electronic mixer and the back-end digitizers. By employing an ultra-stable optical clock, the DISARMER program will allow for mixer-less digitization and thereby improve the dynamic range 100x over the state of the art. Such a wide bandwidth, high fidelity receiver will have applications in electronic warfare and signals intelligence systems while dramatically reducing the cost, size and weight of these systems. The DISARMER program will develop a low jitter mode-locked laser to be used as the sampling source. The program will also develop a novel photonic architecture in a compact platform capable of hybrid electronic-photonic track-and-hold functionality and coherent photo-detection. This program has advanced technology development efforts funded in PE 0603739E, Project MT-15.
