• DESCRIPTION


This is custom designed HF/6M solid state ham radio amplifier, called NEPTUNE, with automatically switched LPF onboard, 2x RD100HHF1 based, intended for mobile operations. This amplifier produced from high quality ORIGINAL parts, such as Mitsubishi transistors and AMIDON cores. PA PCB mounted on metal heatsink for good heat dissipation.  PA has 4 dB flatness of frequency response
