CXE180 - GaAs pHEMT Ultra High Output Broadband Amplifier

For price, see our offline price list section 5.04.

The CXE180 is the latest addition in our extensive range of amplifiers and it might just be the best amplifier there is for distribution or line extender applications. The amplifier’s compact size and light weight brings out its usefulness, while its proven technology gives it plenty of output power. It offers versatility on output configuration and easy operation without the need of plug-in attenuators or equalisers. This new amplifier offers a remarkable combination of reliability and top performance in a small package.

• GaAs pHEMT and MESFET amplifier technology used
• All adjustments with rotary switches
• Dual output - optional
• Improved power dissipation capacity
• Accurate return measurement point
• Excellent ESD and surge protection
• High gain / low gain selection
• Flat / sloped output selection
• Plug-in diplex filters
