WiFi/WiMAX Power Dividers

BroadWave Technologies has expanded its WiFi/WiMAX power divider offering to include four-, six- and eight-way configurations. Model series 151-215-XXX are 50 Ohm, DC to 6 GHz, 1 W units with SMA female connectors. Insertion loss is 1 dB nominal for the four-way configuration across the DC to 6 GHz frequency range. The six- and eight-way configurations’ insertion loss is 1 dB nominal DC to 5 GHz and 1.6 dB nominal 5 to 6 GHz. Maximum VSWR for four-, six- and eight-way configurations is 1.50:1. BroadWave also manufactures model 151-173-002, which is a two-way DC to 6 GHz power divider with SMA female connectors. These devices are ideal for dividing signals for in-building wireless, WiFi, WiMAX, Defense, Homeland Security and Public Safety systems. Weather resistant units and other connector types are also available.
