BBA-322-A

DESCRIPTION
The BBA Series is a family of low-cost high-
performance broadband RF amplifiers. The
modules are ideally suited to a wide range of
amplification and buffering applications,
including extending the range of Linx’s own RF
modules (where legally appropriate). Housed in
a compact SMD package, the hybrid amps are
matched to 50Ω source and load impedances.
The modules utilize a GaHBT gain stage, which
yields high gain and IP3, excellent flatness, and
low noise. The BBA-322-A is the high gain
model and is suitable for the LNA stage of many
receivers. This extra gain stage on the front end
of a receiver can improve the sensitivity and
provide a greater range for the product. The BBA-519-A is the high power model and
is suitable for the final gain stage in a transmitter. This amplifier can boost the output
power of a transmitter to much higher levels and provide a significant increase in
range (where legally appropriate).

is the responsibility of the user to determine and adhere to the appropriate
regulations for the region in which operation is intended.
THEORY OF OPERATION
The BBA Series is a family of low-cost, high-performance, broadband RF
amplifiers. They utilize an advanced Gallium Arsenide Heterojunction Bipolar
Transistor (HBT) gain stage, which yields high gain and IP3, excellent flatness,
and low noise. They are self-contained with 50Ω input and output impedances
and require only one external DC biasing resistor to operate as specified.
The BBA-322-A is the high gain model and is suitable for the LNA stage of many
receivers. This extra gain stage on the front end of a receiver can improve the
sensitivity and provide a greater range for the product.
The BBA-519-A is the high power model and is suitable for the final gain stage
in a transmitter. This amplifier can boost the output power of a transmitter to
much higher levels and provide a significant increase in range (where legally
appropriate).
OPERATIONAL CONSIDERATIONS
The use of a gain stage can produce a significant increase in the range
performance of an RF link. It is important to note that it can also introduce
detrimental effects, such as the following:
Amplification of harmonics and LO along with the fundamental carrier frequency.
Adverse effect on the front-end noise figure on receivers.
Potential damage if the receiver input is not capable of accommodating high
input power levels.
Risk of generating illegal power levels and unacceptable interference.
It is up to the designer to ensure that the final product will comply with all
appropriate regulations in the county of intended use.

-50dBm input unless otherwise
noted. Figure 2 illustrates the
connections necessary for testing
and operation. It is recommended
all ground pins be connected to the
