FEATURES
PRODUCT DESCRIPTION
The AWT921 is a monolithic amplifier for use in
communication systems that require high gain and
output intercept point. This device has been
specifically designed for multi-carrier and micro-cell
base station applications. This device is
• High Power Levels
• High Efficiency
• True Surface Mount Package With Integrated
Heat Slug
• Internal Bias Circuit Requiring Nominal Input
Voltages +10%
• Low Cost
• Off Chip Output Matching Circuit Allows
Application Optimization
APPLICATIONS
• Base Station Driver Amplifier
• u-Cell Base Station Output Stage
• Cellular Booster Amplifier
manufactured on a high power MESFET process
and has an on-chip bias circuit that does not require
highly regulated positive and negative supplies to
establish the proper operating point.
