RM Italy BL 600 Transistor amplifier for HF and 50 MHz

The Bla-600 is a compact 500W transistor power amplifier for short-circuit with built-in power supply. The amplifier works fully automated, without the need for tuning. Badfilter for all bands from 6 to 160m are automatically selected. {

BL-600 Use updated NXP / Freescale mrf6vp5600h modules for energy generation. These modules use 50V power supplies to obtain the best signals of linearity and distortion. The factr amplification is typical 14 db, a piloting power from 20 to 5W is sufficient from 10 to 80, 30-40W are required on 160 and 6m. The amplifier works with all current transceivers, the PTT key can be selected by various methods to accommodate the keyboard on the ground, the systems of open collectors, etc. For a transmission / reception switch without noises, Bla-600 uses Pin diodes, telegraphy speed. {

A 16x2 LC display shows the operating status of the amplifier, further LED bars show the output power level. Various protection circuits monitor several parameters, for example the absorption of current, the voltage, the switch, the temperature, the rotation of the fan etc. This ensures that the amplifier also protects when the antenna works badly. The Bla amplifier has three separate connectors for the antenna which can be assigned to different bands and which will be automatically selected. The built-in power supply can be regulated to various entry voltages, making this amplifier useful for international use, for example to DX-PEDITS. {
