KeyLink Microwave ultra-broadband power amplifier subsystem KB0840S48A is now put into mass production. this rack-mountable unit incorporates a universal voltage power supply and a built in forced air-cooling system. Due to robust engineering and employment of advanced broadband RF matching networks, combining techniques and qualified components, the amplifier achieves consistent performance with field proven reliability.

Built-in monitor circuit helps to survive from any faulty working conditions such as over-driven, load-mismatch and thermal overload.

Digital interfaces as Ethernet and RS232/RS422 are available for remote on/off switch and power level control.
