256-Element Active Antenna Innovator’s Kit
AWA-0142
-
The AWA-0142 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-0135 Silicon Quad Core IC and demonstrates the performance achievable using low power silicon integration and efficient antenna layout and design. Using the AWMF-0135, the antenna provides +60dBmi (1000 W) of EIRP. 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 AWA-0142 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.

DC Filters
-
This DC filter provides substantial noise reduction on DC power lines of up to 50V 9A. Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment or protecting your sensitive equipment from noise coming from DC power supply or other loads. DC filter provides noise suppression for both power lines – positive and negative, plus common-mode noise vs. ground. Filter uses plug-in terminal block for connections and mounting flanges for easy installation. Its rugged construction makes it easy to fit in many industrial tools.
