ADL5320ARKZ-R7 (ANALOG DEVICES)

The ADL5320ARKZ-R7 is a 1/4W RF Driver Amplifier operating from 400 to 2700MHz. The ADL5320 incorporates a dynamically adjustable biasing circuit that allows for the customization of OIP3 and P1dB performance from 3.3 to 5V 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 5V biasing under large signal conditions and then can reduce the 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 22 to 26dBm output power levels.
