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.

Portable Analyzers
The key to the operation of Alpha Moisture Systems' Portable Analysers is the unique Desiccant Dry-Down Chamber. By keeping the sensor dry between tests, the special assembly of the head ensures that the instrument is always ready for immediate use. The head assembly consists of two chambers which have a telescopic action. When the head assembly is in the 'closed' or 'Dry-Down' position, the sensor is completely surrounded by desiccant, which absorbs the remaining water moisture from the sensor and hence it is dry and ready for use. The small space at the bottom of the test chamber enables the sample pipe to be purged before the test commences without wetting the sensor. By placing a finger over the outlet of the head, the sample pressure is able to open the test chamber automatically, exposing the sensor to the gas being tested and enabling accurate reading of moisture content in the sample gas. After each test the head assembly is closed by depressing the inner section so that the sensor will again be dried by the desiccant, leaving the sensor ready for use time and time again. The desiccant is kept in the inner chamber and is not exposed to ambient room air or the sample gas, therefore there is no need for frequent regeneration or replacement of the desiccant.

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.

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.
