Wide temperature 0.5W RF driver amp operates without bias resistor

Analog Devices has introduced the ADL5324 half-Watt RF driver amplifier operating over a wide temperature range (-40° C to +105° C), and can be biased to operate on less power. 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.

ADL5324 Half-Watt RF Driver Amplifier Key Features:
Dynamically adjustable bias to tailor driver performance from 3.3-V to 5-V with a variable or fixed supply; no bias resistor needed
Low power consumption of 62 mA on 3.3 V, up to 133 mA on 5 V, which can be biased anywhere in between these two points
Operates over a frequency range of 400 MHz to 4000 MHz
Best in class performance: OIP3 of 43 dBm, a P1dB of 29 dBm, a gain of 14.6 dB, and a low noise figure of 3.8 dB at 2140 MHz
Robust ESD rating of Class 2, ± 3 kV
Available in the SOT-89 package
