PRODUCT DESCRIPTION
The ADR3410 is a high performance, single-stage
InGaP HBT amplifier designed for use in wireless
infrastructure systems as a highly linear 1 Watt driver.
Packaged in a surface mount 8 pin SOIC, the die is
mounted to a heat slug, offering excellent thermal
dissipation and high reliability. The device may be
biased through an external inductor directly to a +5 V
supply, and uses an internal active bias circuit with a
current adjust input for linearity control.
