mm Wave

What are our 5G solutions?

The wireless industry is working hard to meet the ambitious roll-out plans of mobile service providers for 5G services. WiGig is already available, and the first 5G network will be tested during the Winter Olympics 2018 in South Korea. In parallel, regulators and standards bodies are developing suitable and scientifically sound methods and instrumentation for demonstrating compliance with safety limits of handheld and body-mounted devices operating at frequencies >6 GHz. The safety limits for 5G exposure should be based on the specific absorption rate (SAR) for frequencies below 10 GHz and on surface-averaged power density above 10 GHz.

SPEAG – once more at the forefront of development and innovation – already offers a comprehensive portfolio of solutions to support the design and compliance testing of transmitters developed for emerging 5G technologies. The SPEAG 5G Solution includes SEMCAD X for transmitter design and determination of worst-case exposure configurations, as well as DASY6 or ICEy, with the novel EUmmWV2/SW Module 5G for demonstration of compliance with exposure limits for distances as small as 2 mm from any transmitter.

EM Phantoms

What are EM Phantoms?

EM Phantoms are physical models of the human body that accurately reproduce the effect of the body on electromagnetic (EM) radiation. SPEAG's whole and partial body EM phantoms represent humans in terms of dielectric properties in a wide range of frequencies from <10 MHz to >100 GHz. They enable reproducible and consistent over-the-air (OTA) performance evaluation of wireless devices operating in the proximity of the body.



What is EASY6?

EASY6 is a complete redesign of our widely used Electromagnetic (EM) Exposure Acquisition System EASY4MRI. EASY6 is smaller, more cost-efficient, and connects up to 16 of our classic probes including E- and H-Field, dosimetric, and temperature probes via an optical link (EASY6-DAE + EASY6-EoF + EASY6-RU) to the computer. EASY6 is designed to operate anywhere, including MRI and EM hostile environments.

The product line consists of 1) DAK single probes solutions, 2) DAK Systems, and 3) DAK-TL the first system ever able to measure thin-layer materials and small volumes of liquid



What is MAGPy?

SPEAG’s Magnetic Amplitude and Gradient Probe System (MAGPy) is a cutting-edge all-in-one instrument for fast and reliable compliance testing according to the basic restrictions for wireless power transfer (WPT) systems and any other near-field sources operating at frequencies of 3 kHz − 10 MHz. The device is constructed of 24 small time-domain (TD) loop sensors arranged on the corner of a cube for determining the magnetic (H/B) amplitude and gradient and three dipole sensors to measure the electric (E-) field amplitude. Conservative estimates of the induced E-fields, current density, and specific absorption rate (SAR) in the human body at any position are compared to the basic restrictions, while the incident H/B- and E-fields are compared to the reference levels and displayed in real time in the time or frequency domain (FD) on the intuitive graphical user interface (GUI). By comparison with basic restrictions it lowers the overestimation introduced by compliance testing with reference levels by up to 40 dB. MAGPy is fully compatible with the latest IEC standards.



What are our Time Domain Systems?

The TDS product family offers a wide range of active photonics-based RF measurement solutions operating in the frequency range from 100 kHz – 6 GHz (24 GHz). TDS brings unparalleled sensitivity for EM measurements resolved in the time and frequency domains while maintaining all amplitude and phase information.


OH4VNA - Optical Head for Vector Network Analyzers

OH4VNA is a bi-directional radiofrequency (RF-) over-fiber link that offers the most reliable means to measure the S11 of electrically small antennas in the 500 MHz – 6 GHz frequency range. Previously, in mobile, body-worn, or implanted devices, the exact measurement of the antenna performance was often seriously hindered due to the presence of RF cables connected to antenna, which change the electrical size of the device and, thus, also the impedance of the antenna to be measured. With OH4VNA, we present a new system, one that is based on our proven time domain sensor (TDS) technology, in which the RF cable to the antenna port is replaced by a non-disturbing fiber-optic system that requires no external or battery power. This is a major breakthrough, as this system is transparent to the RF electromagnetic (EM) fields created by the antenna and, therefore, allows the device to be characterized under fully isolated conditions.
