Mini-Circuits is a well-known manufacturer of RF and microwave components, offering a wide range of product lines, including power splitters. A power splitter is a passive device used to divide an input signal equally into multiple output ports. It is widely used in wireless communications, test and measurement, radar systems, and other fields. Below is the key information about Mini-Circuits power splitters, recommended models, and how to choose the right power splitter.

　　1. Power Splitter Overview

　　1.1 Definition

　　Power splitter: A passive device that can divide an input signal into two or more output ports in a certain proportion. It is often used in applications where the same signal needs to be transmitted to multiple loads at the same time.

　　1.2 Types

　　Resistive power splitter: Uses a resistor network to achieve power distribution, suitable for low-frequency applications.

　　** Wilkinson splitter **: Designed with quarter-wave transmission lines and isolation resistors, it can provide good matching and isolation performance over a wide frequency range.

　　Branchline coupler: Power is divided by two transmission lines with a phase difference of 90 degrees, suitable for applications that require phase control.

　　1.3 Application Scenarios

　　Multi-antenna systems: such as cellular base stations, Wi-Fi routers, etc., to ensure that each antenna receives the same signal strength.

　　Test and measurement equipment: used to calibrate and verify the performance of RF circuits.

　　Distributed amplifier: At the front end of the receiver, the signal is evenly distributed to multiple channels for processing.

　　4. Key parameters

　　When selecting a Mini-Circuits power divider, consider the following key parameters:

　　Frequency range: Make sure the selected device can cover the frequency range required by the target application.

　　Insertion loss: The lower the better, indicating less energy loss.

　　Isolation: A measure of the degree of mutual influence between different output ports; higher isolation means better independence.

　　Return loss: Reflects the quality of impedance matching, and the higher the value, the better the matching.

　　Maximum input power: Refers to the maximum input signal power that the device can withstand. Exceeding this value may cause damage.

　　Physical size: Select a product of appropriate size based on the actual installation space.
