The R&K Co. A3000-2H-R is a Class A solid-state power amplifier engineered for RF applications spanning 10 MHz to 3 GHz. It delivers 2 W minimum output power (33 dBm) with 35 dB small-signal gain and ±2.0 dB gain flatness across its operating range. The amplifier operates from 50 Ω source and load impedances, accepting maximum RF input power of +3 dBm and producing typical third-order intermodulation products at +46 dBm.
