RFMW announces availability of a portfolio of devices designed for use in next generation mmWave radio applications. Created by Knowles – DLI, the portfolio includes filters, broadband couplers and Wilkinson power dividers for n257, n258, n260 and n261 bands supporting mmWave 5G designs. The ceramic substrate product line utilizes patented materials exhibiting excellent temperature stability and high K factor. Combined, these characteristics enable off the shelf solutions with small size with high performance. For example, the PDW06984 power divider operates from 25 to 32 GHz with a maximum excess insertion loss of 0.7 dB while consuming just 2.5 mm2 of board space. With excellent repeatability, the couplers are ideal for ultra-compact phased array antenna applications. Evaluation boards are available for qualifying programs.
