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 6 to 160m are automatically selected.
BLA-600 uses upgraded NXP / Freescale MRF6VP5600H modules for power generation. These modules use 50V power supplies to get the best linearity and distortion signals. The factir amplification is typical 14 dB, a driving power of 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 for receiving the touch probe, open collector systems, and so on. For a non-noise transmission / reception switch, BLA-600 uses pin diodes, telegraphy speed.
A 16x2 LC display shows the status of the amplifier, and additional LED bars show the output power level. Various protection circuits monitor various parameters, such as current absorption, voltage, SWR, temperature, fan rotation, and so on. This ensures that the amplifier also protects when the antenna is working poorly. The BLA amplifier has three separate antenna connectors that can be assigned to different bands and will be automatically selected. The built-in power supply can be adjusted to various input voltages, making this amplifier useful for international use, such as DX-pedits.
