Tapper 4.8 dB IP65 300 W 380-3800 MHz 4.3-10 female


Asymmetric power dividers (tappers) for a reliable and cost-effective radio frequency transmission

Tappers, also known as asymmetric power dividers, are passive components used in radio frequency (RF) applications to split off a signal in different shares to output ports. They're integral in optimizing signal strength and quality by dividing off a portion of the power while allowing the rest to pass through.

The Tapper 4.8 dB IP65 300 W 380-3800 MHz 4.3-10 female guarantees excellent, lossless mobile communication quality for use in in-building distributed antenna systems (DAS) or on mobile communication base stations outdoors.

Key characteristics include attenuation level (dB), power handling capacity (W), frequency range (MHz), connector types, and environmental protection rating (e.g. IP 65). Successful tappers must offer precision in attenuation, reliability under varying environmental conditions, and compatibility with a broad range of frequencies and equipment.

Our Tapper 4.8 dB IP65 300 W 380-3800 MHz 4.3-10 female works by dividing the input signal into output signals with a specific splitting ratio of 1 : 0.33 : 0.67 which is required in a variety of RF applications.

Outstanding RF characteristics, best possible passive intermodulation and VSWR

The Tapper 4.8 dB IP65 300 W 380-3800 MHz 4.3-10 female enables you to transmit high-frequency signals reliably and flawlessly with optimum protection of your sensitive equipment in a power range up to Port 1: ≤ 300 W, Port 3: ≤ 100 W with maximum passive intermodulation (IM3) of -155 dBc.

The protection class is IP 65.

The port path designation regarding main line and probe is as follows: Port 1: input, Port 2, 3: output

It supports the use of the following frequency bands : 300, 700, 800, 900, 1500, 1800, 2100, 2300, 2400, 2600, 3800

The 4.3-10 connector system was designed to meet the latest requirements in mobile communication in terms of size, robustness, performance, and other parameters. Its small footprint supports the use of smaller components, mitigates risks if equipment is assembled without due care, and delivers outstanding electrical performance.

A Tapper 4.8 dB IP65 300 W 380-3800 MHz 4.3-10 female has a coupling attenuation of 4.8 dB.

The coupling tolerance is just ±1.5 dB.

Tappers can also be used to match the impedance of different components in an RF system, which is important for maximizing power transfer and minimizing signal insertion loss.
