E&I A300 RF Power Amplifier 300 kHz – 35 MHz 300W
Description
E&I A300 RF Power Amplifier 300 kHz – 35 MHz 300W is a rugged source of RF power, useful for ultrasonic, HF transmitters, RFI/EMI, plasma equipment and general laboratory applications.
FLEXIBILITY:
The A300 produces 300 Watts of class A linear power output over the entire frequency range from 300 kHz to 35 MHz. It has very low harmonic distortion along with low IMD products. Operation over the band is achieved without the need for any band switching or indeed any adjustments. The power gain is rated at 55 dB with a typical gain flatness of ±1.5 dB.
RUGGEDNESS:
The A-300 is built to withstand a 13 dBm input (1.0 Volt RMS) for any VSWR load condition. The internal switched mode power supply is very conservatively rated, to facilitate operation over a large range of line conditions and temperatures. The forced air cooling provides for low internal temperatures, providing long term reliability. The RF power is delivered by rugged DMoS FETs, de-rated to provide for excellent MTBF.
