Coaxial Power Splitter/Combiner 2 Way-0o Resistive 5022 DC to 12000 MHz ZFRSC-123-S+

Category: Electronics, Minicircuits, RF Microwave Devices

Overview

The datasheet provides detailed information on a coaxial power splitter/combiner, specifically the model ZFRSC-123-S+. This device is designed to operate across a very wide bandwidth, from DC up to 12000 MHz. It features excellent phase and amplitude unbalance specifications and is housed in a rugged shielded case. The ZFRSC-123-S+ is also RoHS compliant, with the suffix “+S” indicating this compliance.

Maximum Ratings and Operating Conditions

The power splitter/combiner has a maximum power input of 0.16 watts when used as a splitter and an internal dissipation of 0.8 watts. It can operate within a temperature range from -55°C to 100°C and requires storage within the same temperature limits. Exceeding these ratings may result in permanent damage.

Applications

Due to its excellent performance characteristics, the power splitter/combiner is suitable for use in laboratory settings and for intermodulation distortion (IP3) test setups.

Performance Specifications

The electrical specifications provided are measured at a standard temperature of 25°C ambient. The document outlines the insertion loss, which depends on the frequency range, with a maximum of 19.5 dB from DC to 6000 MHz and a slightly higher maximum of 20 dB from 6000 MHz to 12000 MHz.

Additionally, the datasheet indicates isolation and amplitude unbalance values. Isolation is maintained at 19.5 dB from DC to 6000 MHz, and amplitude unbalance is under 0.25 dB for the same frequency range. The phase unbalance is maintained at a very low value of 3.5 degrees, typical across the full frequency range.

Physical Dimensions

The datasheet reveals the product’s physical outline dimensions, offering these measurements in both inches and millimeters. It also conveys that the power splitter/combiner comes in a standard casing style, JJJ245, and can be ordered with an optional bracket identified as option “B”. The connectors employed are of the SMA model type.

Performance Data and Schematic

The performance data section provides tables and graphs showcasing the device’s response across its operational frequency range, highlighting total loss, insertion loss, VSWR (Voltage Standing Wave Ratio), and amplitude and phase unbalance for specific frequencies.

An electrical schematic is also included, demonstrating the internal configuration of the splitter/combiner.

Availability and Reference Information

The datasheet concludes with notes reinforcing that any performance and quality attributes not expressly stated are excluded from the document. It also clarifies that the published specifications are based on established testing performance criteria and measurement instructions from the manufacturer, Mini-Circuits.
