Richardson RFPD Introduces 1/2-Watt RF Driver Amplifier From ADI

Dynamically-Adjustable Biasing Circuit Allows for Customization of OIP3 and P1dB Performance from 3.3 V to 5 V

Richardson RFPD, Inc. recently announces immediate availability and full design support capabilities for a new 1/2-watt RF driver amplifier from Analog Devices, Inc. (ADI). 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 versatile feature creates the opportunity for dynamic biasing of the device 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.

The ADL5324 is rated to operate across a wide temperature range (−40°C to +105°C), covers a wide frequency range (400 MHz to 4000 MHz), and requires 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.

Additional key features of the ADL5324 include:
• Gain of 14.6 dB at 2140 MHz
• OIP3 of 43.1 dBm at 2140 MHz
• P1dB of 29.1 dBm at 2140 MHz
• Noise figure of 3.8 dB
• SOT-89 package, MSL-1 rated
• ESD rating of ±3 kV (Class 2)

The device is part of ADI's Select Products for Q3, 2012.

Common configurations are in stock and available for immediate delivery. To find more information, or to purchase the device today on the Richardson RFPD website, please visit the ADL5324 webpage.
