This is custom designed HF +50MHz amplifier, called NEPTUNE, with LPF onboard, 4x RD16HHF1 based, intended for field or mobile operations or as driver for LDMOS amplifier. 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 2.5 dB flatness of frequency response and PA can operate 24x7x365 in any digital modes without extra cooling. Nominal power supply - 13.5v. Nominal current is - 7A. Maximum current is - 10A.

Idle current is - 0.8A. Input frequency 1.8, 3.5, 7, 10, 14, 18, 24, 28, 50 MHz. Input and output impedance is 50 Ohm. Input SWR - better than 1.5 for all bands.

Nominal input power is 34dBm (2.5W). Maximum input power is 37dBm (5W). Nominal output power 47dBm (50W CW).

Maximum output power is 48.5dBm (65W CW). Measured IMD3 perfomance is -32dB for nominal power. External PTT signal - GND active. We are open and active, regadless of the war. This is our way of supporting Ukraine's economy.

Postal Service is fully operational where we are. After package leaves Ukraine you can track it through your local Postal web site.
