Typical isolation between ports is 13.1 dB from 10.7 to 13.0 GHz, 19.3 dB from 13 to 22 GHz, and 21.5 dB from 22 to 31 GHz. The resistive/reactive design is fabricated with GaAs MMIC technology and supplied in a surface-mount QFN package that measures 5 × 5 × 1 mm. The EP4KA+ can handle as much as 0.6 W input power as a divider and as much as 0.6 W per port as a combiner. The 50-Ω RoHS-compliant power splitter/combiner exhibits low VSWR of 1.40:1 or better at all ports with excellent amplitude and phase unbalance. It has an operating temperature range of −55 to +105°C and is a good match for broadband communications and test applications.
