Mini-Circuits ZX10-2-183-S+ 1.5–18 GHz 2-Way Power Splitter / Combiner
The Mini-Circuits ZX10-2-183-S+ is an ultra-wideband coaxial 2-way 0° RF power splitter/combiner operating from 1.5 to 18 GHz.
Designed for 50Ω RF and microwave systems, the device combines wide frequency coverage, DC Pass, SMA connectors and high RF power handling in a compact rugged unibody package. Mini-Circuits specifies splitter input power handling of up to 30W from 1.5 to 8 GHz, with frequency-dependent ratings across the remainder of the operating band.
This combination makes ZX10-2-183-S+ particularly useful for broadband signal distribution in RF test equipment, communications systems and defense-related microwave applications.

Frequency-Dependent RF Performance
Because ZX10-2-183-S+ covers more than a decade of bandwidth, insertion loss, isolation and power handling vary with frequency.
| Frequency | Insertion Loss Typical* | Isolation Typical | Max. Splitter Power |
|---|---|---|---|
| 1.5–8 GHz | 0.4 dB | 22 dB | 30W |
| 8–13 GHz | 0.8 dB | 20 dB | 16W |
| 13–17 GHz | 1.0 dB | 20 dB | 12.5W |
| 17–18 GHz | 1.7 dB | 14 dB | 10W |
Amplitude and Phase Balance
Good amplitude and phase matching are important when one RF signal is divided between parallel signal paths.
ZX10-2-183-S+ provides particularly good balance across the lower portion of its operating range.
| Frequency | Amplitude Unbalance Typ. | Phase Unbalance Typ. |
|---|---|---|
| 1.5–8 GHz | 0.10 dB | 1° |
| 8–13 GHz | 0.15 dB | 2° |
| 13–17 GHz | 0.20 dB | 4° |
| 17–18 GHz | 0.40 dB | 4° |
ZX10-2-183-S+ vs ZAPD-21+ vs ZFSC-2-1+
