Mini-Circuits ZFSC-2-1+ 5–500 MHz 2-Way Power Splitter / Combiner

The Mini-Circuits ZFSC-2-1+ is a coaxial 2-way 0° RF power splitter/combiner designed for 5 to 500 MHz operation in 50Ω systems. It features BNC connectors, low insertion loss and high output-port isolation in a rugged shielded enclosure.

The device is intended for VHF/UHF signal distribution, instrumentation and communications applications where one RF signal needs to be divided into two closely matched paths. It may also be used in the reverse direction as a passive RF power combiner when system power and signal conditions are properly considered. 

ZFSC-2-1+ Specifications

Electrical Performance

Mini-Circuits divides the 5–500 MHz operating range into low, middle and upper frequency bands when specifying insertion loss and isolation.

Port Configuration

ZFSC-2-1+ uses three coaxial ports:

Applications

VHF / UHF RF Systems

The 5–500 MHz bandwidth makes ZFSC-2-1+ suitable for signal distribution in VHF and UHF systems, including receiver and RF subsystem testing.

RF Test and Instrumentation

The BNC connectorized construction allows the splitter to be installed easily between signal generators, receivers, spectrum analyzers and other laboratory RF equipment.

Its low amplitude imbalance is useful when the same RF source needs to be distributed to two measurement paths with closely matched levels.

Communication Systems

ZFSC-2-1+ can distribute RF signals between two receivers, monitoring channels or other RF signal paths in communications equipment. Mini-Circuits specifically identifies VHF/UHF, instrumentation and communications systems as target applications.

ZFSC-2-1+ Connector Alternatives

Mini-Circuits offers the same basic 5–500 MHz splitter architecture with different connector options.
