Narda-MITEQ 4456-4 2–18GHz 4-Way Power Divider
Mfr. Part #: 4456-4
Manufacturer:Narda-MITEQ
Product Type: RF/Microwave Power Divider
Frequency Range: 2 GHz to 18 GHz
Configuration: 4-Way
Description: 2 GHz to 18 GHz 4-Way RF Power Divider, SMA Female, 1.8 dB Max Insertion Loss, 18 dB Min Isolation, 30 W
The Narda-MITEQ 4456-4 is a broadband 4-way RF power divider designed to distribute one input signal across four output ports. It covers a wide frequency range from 2 to 18 GHz and uses precision SMA female connectors.
With high isolation between output ports and controlled amplitude and phase tracking, the 4456-4 is suitable for broadband microwave systems requiring consistent four-channel signal distribution. Typical applications include radar, electronic warfare, satellite communications, antenna testing, RF measurement equipment, and multichannel receiver systems.
