The article reports on technologies used to provide real-time, ultra-wideband, radio frequency (RF) signal recording in a small, rugged package optimized for size, weight and power (SWaP). Ultra-wideband RF signal recorders allow to capture large swaths of the RF spectrum for wide bandwidth radar systems and improved Signals intelligence (SIGINT) capabilities.

The article focuses on the advantages offered by new single-ended transistors based on gallium-nitride (GaN) for building next-gen L-band systems. It is noted that the main reasons behind the surge in power is new transistors' greater levels of gain and efficiency. It is also mentioned that both LDMOS and GaN transistors have already replaced bipolar transistors used in traditional avionics and radar.

Recent breakthroughs in radar technology combined with the demand for compact, affordable and high precision radar for military and commercial applications, has led to a renaissance in the methods and use of radar. Many of the upcoming sectors of technology growth, namely autonomous vehicles, unmanned aerial vehicles (UAV) and various commercial/civilian applications, rely upon solid-state radar and new methods of fabrication and programming. This resurgence is a byproduct of escalating advancements in radar, stealth and jamming technologies for defense that is driving conventional radar solutions into obsolescence.1 A wide accessibility to sophisticated digital-signal processing (DSP), agile RF transceivers and cutting-edge anzenna techniques is fueling this accelerating change.

The article offers information on the compound semiconductor, GaN or Gallium nitride and its application for the Space Fence Radar system. GaN uses III/V group elements which enables higher power density and reliability for radio frequency (RF) operation. The Space Fence Radar uses GaN high power amplifiers (HPA) to produce high sensitivity in detecting small objects at reduced number of transmit elements and lower cost.

High-power transmit/receive (T/R) switches for use in multi-channel ice-penetrating imaging radars are capable of sustaining peak power levels exceeding 1000 W. They are based on a balanced topology and built using quadrature hybrids and actively biased PIN diodes. Insertion loss is lower than 1.3 dB from 100 to 350 MHz and lower than 1.6 dB from 150 to 600 MHz. Isolation in transmit mode is higher than 85 dB across both bands with turn-on and turn-off times shorter than 1300 ns and 200 ns, respectively. Both designs were successfully used in multichannel radars for measurements in the Arctic and Antarctic. [ABSTRACT FROM AUTHOR]
