Mini-Circuits ZAPD-21+ 500–2000 MHz 2-Way DC Pass Power Splitter / Combiner

The Mini-Circuits ZAPD-21+ is a coaxial 2-way 0° RF power splitter/combiner designed for 500 to 2000 MHz operation in 50Ω RF systems.

It combines a wide operating bandwidth with 0.25 dB typical insertion loss above the theoretical 3 dB division loss, 25 dB typical isolation, low amplitude and phase imbalance, and up to 10 W RF input power when used as a splitter.

Another important feature is DC Pass. The electrical configuration allows RF and DC to pass through the splitter paths, making ZAPD-21+ useful in RF systems where DC bias and RF signals share the same coaxial connection.

Mini-Circuits identifies applications including UHF, GPS, cellular, PCS/DCS, communications systems and instrumentation.

ZAPD-21+ Specifications

Applications

GPS and RF Distribution

The 500–2000 MHz bandwidth includes frequencies used by several satellite navigation and RF communication systems.

The DC-pass architecture can also be beneficial in RF distribution systems where connected active equipment requires bias power through the coaxial path.

Cellular and PCS/DCS Systems

Mini-Circuits specifically lists cellular and PCS/DCS among the intended applications for ZAPD-21+.

It can be used for:

• Receiver signal distribution

• RF monitoring

• Base-station test setups

• Wireless equipment testing

RF Test & Instrumentation

ZAPD-21+ can split one RF source between two instruments or DUT signal paths.

Its BNC connectorized construction makes it convenient for laboratory and instrumentation environments where the equipment already uses BNC interfaces.

UHF Communications

With operation beginning at 500 MHz, the device is also suitable for selected UHF RF and communications applications requiring a two-way signal distribution architecture.

ZAPD-21+ Connector Options

Mini-Circuits offers the same basic ZAPD-21 configuration with several connector options.

Mini-Circuits currently lists ZAPD-21-S+ and ZAPD-21-N+ as alternative versions of ZAPD-21+.
