High-power RF amplifier for ultracold atom experiments

Abstract

We report on the design and characterization of a high-power amplifier with an output power of 36.5 dBm for a frequency range of 50–1000 MHz with a total gain of 40 dB. The amplifier is optimized for driving acousto-optic and electro-optic modulators for ultracold atom experiments. This amplifier is a 19 in. rack unit, with a power efficiency of >35% and 0.01 dBm long-term stability. Schematics and other design materials are publicly available under an open hardware license.
