Half watt RF driver amplifier with dynamically adjustable bias

To meet the needs of today’s radio and RF communication equipment designers, Analog Devices Inc. (ADI) introduced the ADL5324 half-Watt RF driver amplifier. When compared to other RF driver amplifiers, the ADL5324 offers superior power efficiency and temperature tolerance. The ADL5324 operates over a wide temperature range (-40° to +105°C), and can be biased to operate on less power. In addition, the ADL5324 features dynamically adjustable bias which allows RF designers to set the driver’s power consumption to the performance needs of the system, without the need for a bias resistor. The ADL5324 RF driver amplifier is well-suited for wired and wireless applications including cellular infrastructure, industrial, science, and medical (ISM) band power amplifiers, and defense and instrumentation equipment.
