Success stories and Latest News

Optical interconnect for upgraded military aircraft sub-systems

Military aircraft either consist of rotary-wing or fixed-wing aircraft that are used for combat or surveillance missions, or for the transportation of military personnel and supplies. Many of the global military aircraft fleets are designed to be in service for decades. Nowadays, because of budget constraints, defense administrations are focusing on upgrading and retrofitting the existing fleet of aircraft with advanced avionics, flight control, weapons, and other systems to make their aircraft more efficient and keep pace with the changing nature of modern warfare. In addition, several surveillance systems are being installed in airplanes as emergency warning systems to enhance aircraft situational awareness of pilots and reduce their workload. Special mission airplanes and UAVs are also being deployed for reconnaissance and surveillance missions across land and maritime borders, which necessitates the retrofitting of communication, navigation and surveillance (CNS) systems into existing military fleets.

Smiths Interconnect flies high on F-35 aircraft

Feb 25 2021

Working with principal partners to deliver safety, reliability, and performance

All military programmes are valuable contracts to secure as they are typically long-term commitments that will generate stable future revenue for the businesses. The Lockheed Martin F-35 Lightning II (previously known as Joint Strike Fighter/JSF) programme falls into this category, dating back to the late 1990s when the need for a 5th Generation aircraft began to evolve.
 
The F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole combat aircraft that represent a quantum leap in air dominance capabilities. It is the first 5th generation multi role aircraft to reach service, offering significant updates over previous generation jets. Intended to perform superior air dominance, F-35 are also able to provide electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Integration and interoperability between allies have also been a key driver in the technology development.

Planar Filters Continue to Advance

A primary goal of every RF subsystem today is size reduction — without reducing performance and without increasing cost — while operating at millimeter-wave frequencies that have been only sparsely occupied until now. So, it is interesting that long before surface acoustic wave (SAW) and bulk acoustic wave (BAW) technologies reduced the achievable size of filters by orders of magnitude, the microstrip filter has been doing the same thing since 1952. They remain one of the most important types of filters in engineers’ toolkits, and they have been enhanced over the years through the use of various dielectric substrate materials and design techniques.

High Frequency Spring Loaded Interposers for Space and Defence

Today manufacturers of equipment for applications involved in severe environments have to keep pace with the emerging technologies and system design requirements. Spring Probe Interposers are a mature technology that has been gaining popularity in Defence & Space applications over the last two decades due to their small form factor, light weight, and versatility.


Spring Probe Interposers offer high frequency, high density, low profile, solderless board to board or device to target interconnects that have a high mating cycle life, immunity to shock and vibration, and save weight and space in payloads. Spring Probe Interposers offer a high compliance ratio that can solve board to board tolerance stack issues, have more flexibility for device misalignment and can be blind mated.


Learn from our experts how Spring Probe Interposers can be designed with varying stack heights within the same connector and to exact customer footprints incorporating component cut-outs, latching features and gaskets for ingress or shielding.
