MMIC Power Splitter/Combiner Trims Losses to 18 GHz
Mini-Circuits’ model EP2RKU+ is a two-way, 0-deg., resistive/reactive MMIC power splitter/combiner with a frequency range of dc to 18 GHz. Typical isolation between ports is 13.1 dB from dc to 4 GHz and 26.1 dB from 4 to 18 GHz. Typical insertion loss (above the 3-dB power split) of the EP2RKU+ is 3.3 dB or less from dc to 18 GHz. Amplitude unbalance is typically 0.02 dB across the full frequency range, while the typical phase unbalance is 0.3 deg. to 4 GHz and 1.1 deg. to 18 GHz. The RoHS-compliant power splitter/combiner comes in a surface-mount QFN package that measures just 5 × 5 × 1 mm, but it handles as much as 600 mW of power as a splitter or combiner. The EP2RKU+ exhibits full-band VSWR of 1.50:1 or better at all ports and has an operating temperature range of −55 to +105°C.
