The AGB3303 is one of a series of high performance
InGaP HBT amplifiers designed for use in
applications requiring high linearity, low noise and
low distortion. No external matching components
are needed for insertion into a 50W system. With a
high output IP3, low noise figure and wide band
PRODUCT DESCRIPTION
operation, the AGB3303 is ideal for wireless
infrastructure applications such as Cellular Base
Stations, MMDS, and WLL. Offered in a low cost
SOT-89 surface mount package, the AGB3303
requires a single supply voltage, and typically
consumes 0.6 Watts of power using a +8 V supply.

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.

The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.
Notes:
(1) Operating frequency is defined by the output return loss (S22) having a VSWR less
than 2:1.
(2) Voltage applied through a bias resistor and inductor. Refer to Figure 3. For other
supply voltages, see the APPLICATION INFORMATION section.
