Half watt rf driver amplifier is first to offer dynamically adjustable bias

A new half watt rf driver amplifier said to offer superior power efficiency and temperature tolerance compared to competing devices has been announced by Analog Devices.

The ADL5324 is targeted at wired and wireless applications including cellular infrastructure, industrial, science, medical band power amplifiers and defence and instrumentation equipment.

It operates over a temperature range of -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 amplifier operates over a frequency range of 400 to 4000MHz and has a low power consumption rating of 62mA on 3.3 V and up to 133mA on 5V. It is supplied in an SOT-89 package.
