Product Description


The AN758 HF amplifier is a push-pull linear amplifier for 300 watts of PEP or CW output power across the 2 to 30 MHZ band. One of Motorola's new high-power transistors developed for single-sideband, the MRF429, is used in this amplifier design. The AN758 operates from a 50 Vdc power supply. The amplifier employs a push-pull design for low, even harmonic distortion. This harmonic distortion and the 50 Vdc supply voltage make the output impedance matching easier for 50-Ohm interface and permits the use of efficient 1:1 and 4:1 broadband transformers. Modern design includes integrated circuit bias regulators and the use of ceramic chip capacitors throughout the RF section, making the units easily reproducible.
