Features 

HARDWARE FEATURES: thanks to the modularity of the system make these transmitters ideal for mid-high power applications. Modular concept makes for redundant “N+1” configurations to customer specifications suited for all applications.

POWER & QUALITY: With the creation of the new family of RVR’s high power modular amplifiers based on the M-C & U-K series, is possible to realize compact equipments up to 20kW, extremely redundant, sturdy and flexible. Design solutions ensure the utmost RF efficiency and output power stability with automatic gain control. In addition, by integrating LDMOS technology, is guaranteed an high efficiency.

RELIABILITY & REDUNDANCY (business continuity): elevated number of self-sufficient modules and independent between they, that guarantee the continuity of service with a minimum reduction of the output power. In case of faulty of one or more power supplies, the amplifier continue to work with reduced power.

USER-FRIENDLY FEATURES: user-friendly software and a simple, intuitive HM interface let you easily set up and control all machine operating parameters.

EASE OF MAINTENANCE: accessibility and ease of maintenance are ensured by advanced modular engineering concepts incorporated in the transmitter and by its lightweight components.

REMOTE CONTROL: the device comes with a powerful and complete telemetry system, available optionally.
