400 MHz to 4000 MHz Watt RF Driver Amplifier Data Sheet ADL5324 FEATURES FUNCTIONAL BLOCK DIAGRAM GND Operation from 400 MHz to 4000 MHz (2) Gain of 14.6 dB at 2140 MHz ADL5324 OIP3 of 43.1 dBm at 2140 MHz P1dB of 29.1 dBm at 2140 MHz Noise figure of 3.8 dB BIAS 1 2 3 Dynamically adjustable bias RFIN GND RFOUT Adjustable power supply bias: 3.3 V to 5 V Figure 1. Low power supply current: 62 mA to 133 mA No bias resistor needed Operating temperature range of 40C to +105C SOT-89 package, MSL-1 rated ESD rating of 3 kV (Class 2) APPLICATIONS Wireless infrastructure Automated test equipment ISM/AMR applications GENERAL DESCRIPTION The ADL5324 incorporates a dynamically adjustable biasing The ADL5324 also delivers excellent ACPR vs. output power and circuit that allows for the customization of OIP3 and P1dB bias voltage. The driver can deliver greater than 17 dBm of output performance from 3.3 V to 5 V, without the need for an external power at 2140 MHz, while achieving an ACPR of 55 dBc at 5 V. If bias resistor. This feature gives the designer the ability to tailor the bias is reduced to 3.3 V, the 55 dBc ACPR output power driver amplifier performance to the specific needs of the design. only minimally reduces to 15 dBm. This feature also creates the opportunity for dynamic biasing of 30 the driver amplifier where a variable supply is used to allow for 35 full 5 V biasing under large signal conditions, and then reduced 40 supply voltage when signal levels are smaller and lower power 45 consumption is desirable. This scalability reduces the need to 50 evaluate and inventory multiple driver amplifiers for different 55 output power requirements, from 25 dBm to 29 dBm output SOURCE 60 V = 3.3V power levels. CC V = 5V 65 CC The ADL5324 is also rated to operate across the wide temperature 70 range of 40C to +105C for reliable performance in designs 75 that experience higher temperatures, such as power amplifiers. 80 The W driver amplifier also covers the wide frequency range 85 of 400 MHz to 4000 MHz, and only requires a few external 20 15 10 5 0 5 10 15 20 25 P (dBm) components to be tuned to a specific band within that wide range. OUT This high performance broadband RF driver amplifier is well Figure 2. ACPR vs. Output Power, Single Carrier W-CDMA, TM1-64 at 2140 MHz suited for a variety of wired and wireless applications, including cellular infrastructure, ISM band power amplifiers, defense equipment, and instrumentation equipment.
