Radio equipment maker Bext has several new products for the NAB Show.
The FB5000 is a new solid-state FM amplifier with up to 5 kW of power. The whole unit is designed to fit into 4 RU. The company touts it for its high-efficiency Mosfet design, automatic gain control for fixed output power even when drive power fluctuates, and its reliability and easy handling. The amplifier is broadband, so no tuning is required.
Other features include proportional auto-foldback of output power in the case of excessive VSWR; protection against excessive temperature and drive power; and modulare construction. Remote control and telemetry capability is built in, with main parameters on rear contacts.
Also new is the latest member of the Lex family of FM exciters. The Lex 150 is the biggest of the bunch at 150 W of power but still only 1 RU in size. An internal stereo generator is included along with a limiter and programmable FSK ID keyer. Audio inputs include SCA/RDS, aux, MPX and L/R. An LCD display can offer status messages and diagnostics. An internal blower helps keep things cool. It can operate as a standalone transmitter.
