Agilent MSA-2743
Cascadable Silicon Bipolar
Gain Block MMIC Amplifier
Data Sheet
Applications
• Cellular/PCS/WLL basestations
• Wireless data/ WLAN
• Fiber-optic systems
• ISM
Description
Agilent Technologies’ MSA-2743 is
a low current silicon gain block
MMIC amplifier housed in a 4-lead
SC-70 (SOT-343) surface mount
plastic package.
Providing a nominal 15.5 dB gain
at up to 15 dBm Pout, this device
is ideal for small-signal gain stages
or IF amplification.
The Darlington feedback structure
provides inherent broad band-
width performance. The 25 GHz f
t
fabrication process results in a
device with low current draw and
useful operation to past 3 GHz.
