Thermal Shock Chambers
We provide a large selection of thermal shock chambers to accommodate various types of product testing. Thermal Shock Chambers perform tailored environmental stress screening of component and board electronic assemblies. Our unique chamber design transfers product between two extreme temperature-controlled chambers, passing equal volumes of high velocity conditioned air over the product and resulting in rapid product temperature changes. The induced thermal stresses can reveal hidden manufacturing defects in electronic sub-assemblies and other components by the expansion and contraction of critical parts.

High Current Switches
B-1002
Ross High Current Switches are available up to 36,000 amps continuous and over 1,700,000 amps 20µsec RC pulse, with voltage ratings of 6 volts to 400kV peak test. Standard Ross high current switches are built with 80 to 120psi air cylinder actuators. Air cylinder or motor operated for high contact force. Arcing contacts optional for closing current. G-10 epoxy glass laminate is standard insulation on most models. G-7 silicone glass is used on models available for RF applications above 100kHz. Most Ross high current switches are available with additional lengths of insulation, where the high voltage contacts need to be spaced at a greater distance from the actuator and control circuit. Voltage withstand value is at least doubled and the interrupt capability is much greater when high current switches are immersed in insulating oil, fluid or SF6 gas. For gas atmosphere, no modifications are necessary; however, oil or fluid immersion requires modification at a slight extra cost.

Broadband Antenna
Vivaldi
The dbDIRECT Broadband Antenna features a broad frequency range of operation, high gain, small form factor and directional radiation pattern, making it highly attractive for widespread use in test and measurement of emerging wireless technology devices and radars. Contrary to conventional Vivaldi antennas limited to operating only at higher frequencies, the dbDIRECT Broadband Antenna design is optimized to operate at a frequency as low as 700 MHz up to 6 GHz. This lightweight and compact antenna design provides excellent matching over a broad frequency range.The antenna is designed to be placed in a DVTEST's portable anechoic chamber such as the dbSAFE enclosures for OTA (Over the Air) testing of DUTs. The antennas can be mounted in fixed positions to facilitate repeatable results. When used in conjunction with a rotary positioning mechanism, customers are able to detect the highest point of power sensitivity for enhanced accuracy and repeatability in measurements. In this configuration, both the antennas and DUTs can be positioned in order to facilitate the measurement.

5G Active Antenna Innovator’s Kit
AWMF-0129
The AWMF-0129 is an active array for 5G wireless applications developed using planar antenna technology resulting in a very low profile, lightweight unit. The surface mount assembled antenna board is based on Anokiwave’s AWMF-0108 Silicon Quad Core IC and demonstrates the performance achievable using low power silicon integration and efficient antenna layout and design. Using the AWMF-0108, the antenna provides +50dBmi output power while consuming just 12W DC power in the RF circuits and has achieved Gb/s data rates in OTA trials. The electronic 2D beam steering is achieved using analog RF beam forming, with independent phase and gain control in both Tx and Rx operating modes. The AWMF-0129 antenna leads the way in showing how 5G coverage can be rolled out by network operators using the mmW bands, with low power footprint and high energy efficiency, while meeting key operating specifications for data rate, latency, coverage, and reliability.

RF & Microwave Passive Components
SHF Communication Technologies AG
SHF’s microwave components are broadband devices suitable up to 110 GHz. Our SHF BIAS TEES are well known but perhaps a slight variation does suit your application even better. DIPLEXERS are bias tees with a certain bandwidth in the low frequency path to combine or separate high frequency and low frequency signals into or out of a single line. DC-FEEDERS are bias tees without the capacitor. Therefore, it provides slightly lower insertion loss in case it is connected to an AC-coupled device which already has a capacitor on its input. Based on our air line construction, these passive components provide resonance-free transmission over the entire operating range.

External Frontend
FE50DTR
The R&S®FE50DTR external frontend can extend the frequency range up to 50 GHz for Rohde&Schwarz signal and spectrum analyzers as well as signal generators. The R&S®FE50DTR enables signal up and downconversion directly at the device under test (DUT), lowering cable losses, increasing sensitivity and delivering more power at the antenna in an OTA environment. With a dual connector system, testing of active components is an easy task.
