GENERAL DESCRIPTION
The ADL5324 incorporates a dynamically adjustable biasing
circuit that allows for the customization of OIP3 and P1dB
performance from 3.3 V to 5 V, without the need for an external
bias resistor. This feature gives the designer the ability to tailor
driver amplifier performance to the specific needs of the design.
This feature also creates the opportunity for dynamic biasing of
the driver amplifier where a variable supply is used to allow for
full 5 V biasing under large signal conditions, and then reduced
supply voltage when signal levels are smaller and lower power
consumption is desirable. This scalability reduces the need to
evaluate and inventory multiple driver amplifiers for different
output power requirements, from 25 dBm to 29 dBm output
power levels.
The ADL5324 is also rated to operate across the wide temperature
range of −40°C to +105°C for reliable performance in designs
that experience higher temperatures, such as power amplifiers.
The ½ W driver amplifier also covers the wide frequency range
of 400 MHz to 4000 MHz, and only requires a few external
components to be tuned to a specific band within that wide range.
This high performance broadband RF driver amplifier is well
suited for a variety of wired and wireless applications, including
cellular infrastructure, ISM band power amplifiers, defense
equipment, and instrumentation equipment. A fully populated
evaluation board is available.

The ADL5324 also delivers excellent ACPR vs. output power and
bias voltage. The driver can deliver greater than 17 dBm of output
power at 2140 MHz, while achieving an ACPR of −55 dBc at 5 V. If
the bias is reduced to 3.3 V, the −55 dBc ACPR output power
only minimally reduces to 15 dBm.
