MT1110 RF AMPLIFIER
PRODUCT BRIEF
The MT1110 RF amplifier is designed
for broadband CATV distribution, car
TV applications, and infrastructure
applications.
MT1110 RF Amplifier
The Microtune MT1110 radio
frequency (RF) amplifier is a 75Ω
internally matched amplifier
designed for broadband CATV
distribution, car TV applications, and
infrastructure applications.
The MT1110 is built using high-
performance silicon-germanium
(SiGe) technology and offers 15 dB
gain with an industry best noise
figure of 3.0 dB. It achieves a third-
order intercept point of 80 dBmV
while drawing the industry’s lowest
current, 76 mA, from a single 5V
supply.
The MT1110’s Darlington circuit
topology produces high linearity
with very low noise, while
maintaining matched input and
output impedances. Two AC
coupling capacitors, a bias resistor,
and an optional inductor are the only
external components required.
The MT1110 is available in an
SOT-89 package for the extended
industrial and automotive
temperature range of -40°C to
+85°C.
The MT1110 is highly suitable for
applications such as car TV antenna
amplifiers or splitters for car TV
receivers.
