AWM6423
OVERVIEW
ANADIGICS AWM6423 WiMAX Power Amplifier high performance device that delivers exceptional linearity efficiency high levels output power. device shut down without disconnecting from main power supply (nominally +2.9 +4.2 dropping bias voltage (Pin below +0.7 Using application circuit detailed AWM6423 product data sheet, this "shut down" "off" state, device will draw about current from negligible current from Pins applications which power supply battery source minimal power consumption state critical, AWM6423 application circuit re-configured such that state current draw becomes less than altogether.
STATE LEAKAGE CURRENT APPLICATION CIRCUIT
connecting AWM6423 bias voltage input (Pin instead main power supply, circuitry that draws current from effectively shut down, total leakage current from AWM6423 reduced less than (see Figure this configuration, typical current consumption from +2.85 bias voltage (for Pins combined) approximately using +3.3 main supply.
