Acom 2020S MOSFET linear amplifier 1500W 1.8-54 MHz

ACOM 2020S two LDMOS modules

1.8–54 MHz solid-state linear amplifier with two LDMOS power modules, 7" touch display, Ethernet and Wi-Fi remote control

The ACOM 2020S is a solid-state linear amplifier for the bands from 1.8 to 54 MHz, with two LDMOS power modules combined and fully automatic band switching.

Product description

When connected via CAT it follows the transceiver's operating frequency; even without CAT the built-in frequency counter measures the input signal and changes band automatically.

All status information is shown as text on the 7" colour touch display of the remote control unit (155 × 90 mm, 1024 × 600 pixels, 24 bit). All controls, except the mains switch and power indicator, are on the touch screen and menu-driven.

It is compatible with any transceiver: only the "ground on TX" command and RF drive power are needed. The two output stages use MRFX1K80HR5 LDMOS transistors or equivalent, in a power splitting and combining configuration. The broadband input has an SWR below 1.2 (typically 1.1) across the whole range, with no retuning.

The protections work continuously; the operator can monitor 11 operating parameters, and the memory stores 55 parameters for each of the last 28 protection trips. It can be controlled remotely over the Internet via the built-in web interface, RJ45 Ethernet port and Wi-Fi adapter.

The built-in switching power supply with PFC operates at 200–240 V AC ± 10% (limits 180–264 V) without switching, with sinusoidal current and limited inrush: also suitable for generators and unstable mains.
