Output power indicator
Protected against polarity inversion, over temperature, over input power and high SWR
6 output low pass filters can be set manually or selected in automatic way by processor
The HLA-300V is an high-power linear amplifier designed to operate in all modes on all HF ham radio bands (1.8-30 Mhz). In order to significantly reduce the harmonic emissions, it has been equipped with filters (elliptical) with cutting frequencies of 3/4.5/8/15/22/31 Mhz. A microprocessor supervises on all amplificatory functions:
➢ Detects the input frequency and sets the related filter when the amp is in AUT. mode;
➢ Detects the input power and, if too high, puts on the -3dB attenuator to halve it.
➢ Checks the antenna stationary waves and shutdowns the amplifier if the SWR is too high.
