The **ZCSC-3-R3+** is a coaxial 3-way power splitter/combiner manufactured by Mini-Circuits. It is designed to operate within a specific frequency range, splitting an input signal into three equal-phase output signals or combining three signals into one. --- ## Technical Specifications The following table summarizes the key electrical and physical characteristics of the ZCSC-3-R3+: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 2 MHz to 300 MHz | | **Insertion Loss (Above 4.8 dB)** | 0.4 dB (Typical) | | **Isolation** | 30 dB (Typical) | | **Amplitude Unbalance** | 0.1 dB (Typical) | | **Phase Unbalance** | 1.0° (Typical) | | **VSWR (Input/Output)** | 1.15:1 / 1.1:1 | | **Maximum Power Input** | 1 Watt (as a splitter) | | **Connector Type** | SMA Female | | **Operating Temperature** | -55°C to 100°C | --- ## Key Features and Components ### 1. Internal Circuitry The device utilizes a **Wilkinson-style power divider** topology implemented with high-quality ferrite cores and wire-wound transformers. This ensures low loss and high isolation between the output ports. ### 2. Physical Construction * **Housing:** The unit is encased in a rugged, shielded metal case (Case Style: M21) to prevent Electromagnetic Interference (EMI). * **Connectors:** It features gold-plated SMA connectors for reliable signal integrity and corrosion resistance. * **RoHS Compliant:** The "+" suffix indicates that the part is lead-free and meets RoHS standards. ### 3. Functional Applications * **Signal Distribution:** Splitting a single RF source to three different receivers. * **Antenna Arrays:** Feeding multiple antenna elements with synchronized phases. * **Test and Measurement:** Distributing a clock or reference signal across multiple test benches. --- ## Performance Summary The ZCSC-3-R3+ is favored in HF and VHF applications due to its **low insertion loss** and **high isolation**. High isolation is critical because it prevents a fault or impedance mismatch at one output port from significantly affecting the signal quality of the other two ports.
