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.

Two Channels, 2400MHz TDD Application

Product Detail

The AD-PZSDR2400TDD-EB is a 2.4GHz TDD analog module designed to work with the AD9361, a high performance, highly integrated RF transceiver intended for use in RF applications, such as 3G and 4G base station and test equipment applications, and software defined radios. The AD-PZSDR2400TDD-EB is affectionately dubbed the first 'RF personality card'. It plugs into the ADRV1CRR-FMC carrier card. 35mm U.FL coaxial cables connect the card to the ADRV9361-Z7035 SDR SOM providing access to the transmit and receive inputs of the AD9361. Information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found on the wiki page.


The purpose of the AD-PZSDR2400TDD-EB is to provide the user with a path to condition the transmit or receive signals of the AD9361. Selection of TX or RX path is achieved by the 200MHz to 2.7GHz SPDT switch HMC546 controlled by the FPGA and accompanying software. The transmit path consists of a 2.4GHz filter, half watt driver amplifier ADL5324 and 2 watt power amplifier HMC921. The receive path consists of the same 2.4GHz filter as well as a low loss LNA HMC669.

Product Detail

ADL5324-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a single 5 V/500 mA supply. The 5 V supply should be connected to the test loops labeled VSUP and GND. The RF input is applied to the SMA connector labeled RFIN. The RF output is available at the SMA connector labeled RFOUT. To facilitate tuning for different frequencies the RF input and RF output traces are free of solder mask and have index markings for ease of component placement. The evaluation board ships with tuning components that are optimized for operation from 2110 MHz to 2170 MHz. The ADL5324 datasheet provides recommended tuning components for other frequencies.
