Werbel Microwave has successfully prototyped and is developing what will become a line of GPS splitters in both active and passive configurations, from 2 to 16 branches. With DC blocking and load resistors on outputs in any or all configuration, per customer requirement. VSWR is < -15dB and insertion loss is 0 +/- 1 dB. Isolation is 18 dB minimum. +5VDC supply for active splitters can be connected by feed-through or bias tee.
