2.3 GHz to 4.0 GHz Watt RF Driver Amplifier Data Sheet ADL5321 FEATURES FUNCTIONAL BLOCK DIAGRAM GND Operation: 2.3 GHz to 4.0 GHz (2) Gain of 14.0 dB at 2.6 GHz OIP3 of 41.0 dBm at 2.6 GHz ADL5321 P1dB of 25.7 dBm at 2.6 GHz Noise figure: 4.0 dB at 2.6 GHz BIAS Power supply voltage: 3.3 V to 5 V 1 2 3 Power supply current: 37 mA to 90 mA RFIN GND RFOUT Dynamically adjustable bias No bias resistor required Figure 1. Thermally efficient, MSL-1 rated SOT-89 package Operating temperature range: 40C to +105C ESD rating of 2 kV (Class 3A) APPLICATIONS Wireless infrastructure Automated test equipment ISM/AMR applications GENERAL DESCRIPTION The ADL5321 incorporates a dynamically adjustable biasing The ADL5321 also delivers excellent adjacent channel leakage ratio (ACLR) vs. P circuit that allows for the customization of OIP3 and P1dB OUT. For output powers up to 10 dBm rms, the performance from 3.3 V to 5 V without the need for an external ADL5321 adds very little distortion to the output spectrum. At bias resistor. This feature gives the designer the ability to tailor 2.6 GHz, the ACLR is 59 dB and a relative constellation error of driver amplifier performance to the specific needs of the design. 46.6 dB (<0.5% EVM) at an output power of 10 dBm rms. This feature also creates the opportunity for dynamic biasing of 30 the driver amplifier, where a variable supply is used to allow for ADJ CH LOW 2.6 GHZ ALT CH LOW 2.6 GHZ full 5 V biasing under large signal conditions and then can 40 ADJ CH LOW 3.5 GHZ reduce the supply voltage when signal levels are smaller and ALT CH UP 3.5 GHZ lower power consumption is desirable. This scalability reduces 50 the need to evaluate and inventory multiple driver amplifiers for different output power requirements from 22 dBm to 60 26 dBm output power levels. 70 The ADL5321 is also rated to operate across the wide temper- ature range of 40C to +105C for reliable performance in 80 designs that experience higher temperatures, such as power 90 amplifiers. The watt driver amplifier covers the 2.3 GHz to 10 5 0 5 10 15 20 4.0 GHz wide frequency range and only requires a few external P (dBm) OUT components to be tuned to a specific band within that wide Figure 2. WiMAX 64 QAM, 10 MHz Bandwidth, Single Carrier 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.
