PRODUCT DESCRIPTION
The AGB3300 is one of a series of GaAs MESFET
amplifiers designed for use in applications
requiring high linearity, low noise and low distortion.
With a high output IP3, low noise figure and wide
band operation, the AGB3300 is ideal for 50W
wireless infrastructure applications such as Cellular
Base Stations, MMDS, and WLL. Offered in a low
cost SOT-89 surface mount package, the AGB3300
requires a single +5V supply, and typically consumes
700 mW of power.

Stresses in excess of the absolute ratings may cause permanent
damage. Functional operation is not implied under these conditions.
Exposure to absolute ratings for extended periods of time may
adversely affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however,
parametric performance is guaranteed only over the conditions defined
in the electrical specifications.
