COMARK Communications is the leading supplier of RF amplifier systems up to 1.3 GHz in frequency and 2MW of RF power. We have delivered several turn-key amplifier and HVPS systems for synchrotrons, cyclotrons, ion cyclotron resonance heating (ICRH), linear accelerators, and high powered industrial RF sources. COMARK’s RF amplifier solutions typically encompass not only the RF circuits, but also the control system, HV power supplies, and associated cooling circuits.

Drawing on its vast experience in this field, COMARK along with our partner Ampegon ( in Turgi, Switzerland, designs and delivers special RF amplifier systems such as applied for gridded tubes, klystrons, gyrotrons, tetrodes, or inductive output tubes (IOT). In addition to RF sources, solutions are available for high voltage power supplies (HVPS) as well as digital low level RF (LLRF) systems. Our customers include renowned laboratories, research institutes and private institutions on 5 continents.

The COMARK Scientific and Industrial IOT Amplifier (SIIA) family is adapted from the highly successful, field-proven IOX and DCX family of high power IOT UHF television broadcast transmitter line. COMARK has supplied hundreds of IOT amplifiers and RF systems with power ranges from 30kW to 300kW in analog and digital modulation techniques.
