Mini-Circuits is offering a new broadband power splitter/combiner covering 1.8 to 12.5 GHz in a compact 4 × 4 mm surface-mount plastic package.
The ports of the EP2C+ are tightly matched, with the typical amplitude imbalance only 0.1 dB from 1.8 to 3.8 GHz, 0.2 dB from 3.8 to 8.5 GHz and 0.7 dB from 8.5 to 12.5 GHz. When used as a power splitter, the two output ports are in phase, with the typical phase imbalance 3, 6 and 11 degrees, respectively, across the 1.8 to 3.8, 3.8 to 8.5 and 8.5 to 12.5 GHz frequency segments. Added insertion loss above the theoretical 3 dB power split is typically 0.8, 1.1 and 1.8 dB across the same frequency bands. Isolation is typically 10 dB at the low end of the frequency range and 17 dB at the upper end. VSWR is low, typically no greater than 1.5:1 at the common port and 1.6:1 at either of the two legs.
As a splitter, the EP2C+ will handle up to 1.85 watts input power and is designed to operate from -40º to +85ºC. The RoHS compliant device has a Class 2 human-body model (HBM) ESD rating. Containing no blocking capacitors, the frequency response of the EP2C+ extends to DC, and it will carry up to 400 mA current.
