RFMW announces design and sales support for MECA Electronics broadband power divider/combiners. The 802-2-4.250 RF power divider/combiner offers 2-way, in-phase performance from 0.5 to 8 GHz. Capable of handling up to 30 Watts of average power with an operating temperature of -55 to +85 degrees C, it offers phase and amplitude balance generally seen only in narrow band models. Typical insertion loss is 0.8 dB with 22 dB isolation. Available in 4-way and 8-way versions as 804-2-4.250 and 808-2-4.250 respectively, the broad band nature of these power divider/combiners eliminates the need to increase the component count in D.A.S systems.
