L- and S-Band High Gain Amplifiers

Pasternack Enterprises (Irvine, CA) has announced a new portfolio of Land S-band high gain amplifiers. The modules, packaged in hermetically-sealed metal enclosures, are optimized for 1.2 – 1.4 GHz and 3.1 – 3.5 GHz radar applications. The RF amplifiers utilize a hybrid microwave integrated circuit design and GaAs pHEMT technology. The devices also feature built-in voltage regulation, bias sequencing, and reverse bias protection.

Reaching the Benchmark in Secure Unmanned Vehicle Software

Security concerns currently dominate software thinking wherever sensitive or safety-critical information is potentially accessible. Embedded software is no exception. Security researcher Barnaby Jack demonstrated this in 2011 when he used a modified antenna and software to wirelessly attack and take control of Medtronic’s implantable insulin pumps. He demonstrated how such a pump could be commanded to release a fatal dose of insulin. Obviously, that vulnerability puts dependent diabetics at risk.

Submersion and Directed Flow Cooling Technology for Military Applications

As the US military shifts from boots on the ground to drones in the sky, there will be an increasing need for computing power on foreign soil, under the sea and in the air. Design objectives will be difficult to achieve with legacy technology. Electronic gear must be deployed by transport plane and require rapid setup once the destination is reached. Systems will need to be hardened to survive extreme temperatures, desert sand, salt air and pollution. Fuel logistics to serve remote locations can be difficult and expensive. Every kilowatt-hour of electricity converted to heat must be dissipated and, ideally, the waste energy should be recycled. For ground installations, it will be useful to consider distributing computing resources around rather than concentrating them at a single location that may be vulnerable to attack. Silent operation also is desirable.

Avionics Heat Up, in a Good Way

The common feature shared by recent aviation platforms is the high level of systems integration, and the way in which information is displayed or made accessible, allowing previously unimaginable levels of situational awareness to be available to pilots and ground controllers. This has greatly eased the pilot workload and enhanced flight safety, especially when flying in poor weather or operating in unfamiliar or hazardous terrain.

Airborne Antenna Considerations for C-Band Telemetry Systems

It is fairly well known within the aerospace community that telemetry is moving from the traditional L-band and S-band frequency ranges up to C-band. It is widely understood that the reason for this push to C-band is two-fold. First, traditional L and S frequency bands have been greatly reduced through reallocation for a variety of reasons by different markets, and second, the bandwidth required for most applications has seen exponential growth. This has not only been seen in military applications, but in civilian aerospace platforms as well.

Software-Designed System Improves Wireless Test Speed and Coverage

As wireless standards become more complex, the number of operational modes for these devices increases exponentially. As progression continues to the latest WiFi standard, new modulation schemes, more channels, more bandwidth settings, and additional spatial streams are added. Additionally, characterizing WLAN transceivers is especially challenging when faced with thousands of independent operational gain settings.
