RF amplification for compact drone platforms with limited SWaP For RF systems onboard drones, size, mass and power consumption are important design criteria. At the same time, sufficient output power is required for RF payloads over a broad frequency range. A compact amplifier module can simplify integration of the RF chain. The AMP10008 from Exodus…
RF switching and signal level control in automated RF testing In automated RF testing, signals often need to be switched between test equipment and the device under test, while their levels are adjusted. With multiple test paths, this can result in a complex setup with many individual components. Switch and attenuator boxes combine these functions…
RF absorber reduces reflections in test setups and antenna structures Unwanted reflections are a recurring problem in almost every RF environment: signals reflecting from a test enclosure or crosstalk between antenna systems. ABS Technics offers ABS-SLF-F-x V, a fully encapsulated, lightweight, carbon-loaded foam absorber that addresses this over a broad frequency range. The absorber consists…
NIR filter blocks visible light for optical sensors For sensors that use near-infrared (NIR) light, visible and ultraviolet light can affect detection. This applies to machine vision, iris scanners, LiDAR, time-of-flight modules and other optical sensors. A filter in the sensor window can block unwanted wavelengths before they reach the detector. Solaris S306 is an…
Mobile command post with RF shielding for secure communications Modern command posts need to be rapidly deployable, easy to relocate, and provide protection against eavesdropping and electromagnetic interference. A textile-based, RF-shielded shelter provides a practical solution by combining low weight with high shielding effectiveness and short setup time. The modular construction can be used as…
Microwave absorption prevents resonances and cross-coupling up to 100 GHz In compact high-frequency systems, metal enclosures, cavities and other structural components can cause unwanted microwave resonances and mutual coupling. In 77 GHz radar systems for ADAS driver assistance systems, this can affect signal integrity and therefore system operation. One solution is to locally absorb electromagnetic…
High-power RF amplifiers for ground-based drone detection systems Ground-based RF systems for detecting drones generally operate at higher power levels than compact RF systems used in airborne platforms. The amplifiers used must also cover a broad frequency range and continue to operate reliably under mobile conditions, including exposure to shock, vibration and heat generation. Exodus…
Flexible EMI/RFI shielding for complex PCB layouts Tight PCB layouts, mixed-signal designs and frequent design changes make it difficult to effectively protect sensitive circuits against EMI/RFI. A standard shield does not always match the final PCB layout, while a fully custom shield involves additional development time and tooling costs. A two-piece board-level shielding system provides…
Ferrite materials for wireless power transfer In wireless power transfer (WPT), ferrite materials are used to influence the magnetic flux field of the transmitting and receiving coils. Ferrite can guide the magnetic flux in the desired direction and limit coupling with surrounding metal and electronic components. Material selection depends, among other factors, on operating frequency,…
The Shieldex Faraday Bag is designed to protect electronic equipment from unauthorized access as well as from external RF signals that could affect the operation or configuration of the electronics. The material is made from the conductive non-woven Shieldex Zeven+30, which provides shielding performance of up to 90 dB on average across the frequency range of…
