ADL5324ARKZ 射频放大器

ADL5324ARKZ

射频放大器 Sot-89 1/2 W RF Driver Amplifier

400 MHz to 4000 MHz  ½ Watt RF Driver Amplifier

GENERAL DESCRIPTION  ADL5324ARKZ

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 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 5 V biasing under large signal conditions, and then reduced  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 25 dBm to 29 dBm output  power levels.
