400 MHz to 2700 MHz Watt RF Driver Amplifier Data Sheet ADL5320 FEATURES FUNCTIONAL BLOCK DIAGRAM GND Operation: 400 MHz to 2700 MHz (2) Gain of 16.9 dB at 880 MHz ADL5320 OIP3 of 45.0 dBm at 880 MHz P1dB of 25.4 dBm at 880 MHz BIAS Noise figure: 4.1 dB at 880 MHz 1 2 3 Power supply voltage: 3.3 V to 5 V RF GND RF IN OUT Power supply current: 44 mA to 104 mA Dynamically adjustable bias Figure 1. No bias resistor required Thermally efficient, MSL-1 rated SOT-89 package Operating temperature range: 40C to +105C ESD rating of 4 kV (Class 3A) APPLICATIONS Wireless infrastructure Automated test equipment ISM/AMR applications GENERAL DESCRIPTION The ADL5320 incorporates a dynamically adjustable biasing The ADL5320 also delivers excellent adjacent channel power circuit that allows for the customization of OIP3 and P1dB ratio (ACPR) vs. output power and bias voltage. The driver can performance from 3.3 V to 5 V without the need for an external deliver greater than 17 dBm of output power at 2140 MHz while bias resistor. This feature gives the designer the ability to tailor achieving an ACPR of 55 dBc at 5 V. If the bias is reduced to driver amplifier performance to the specific needs of the design. 3.3 V, the 55 dBc ACPR output power reduces to 9 dBm. This feature also creates the opportunity for dynamic biasing of 20 the driver amplifier, where a variable supply is used to allow for 30 full 5 V biasing under large signal conditions and then can reduce the supply voltage when signal levels are smaller and lower power 40 consumption is desirable. This scalability reduces the need to SOURCE evaluate and inventory multiple driver amplifiers for different 50 V = 5V CC V = 3.3V CC output power requirements from 22 dBm to 26 dBm output 60 power levels. The ADL5320 is also rated to operate across the wide temperature 70 range of 40C to +105C for reliable performance in designs 80 that experience higher temperatures, such as power amplifiers. 1 The 4 watt driver amplifier also covers the 400 MHz to 2700 MHz 90 wide frequency range and only requires a few external components 20 15 10 5 0 5 10 15 20 P (dBm) to be tuned to a specific band within that wide range. This high OUT performance, broadband RF driver amplifier is well suited for a Figure 2. ACPR vs. Output Power, Single Carrier W-CDMA TM1-64 at 2140 MHz variety of wired and wireless applications including cellular infrastructure, ISM band power amplifiers, defense equipment, and instrumentation equipment.
