The Microtune 1110 (MT1110) broadband amplifier is a 75Ω internally matched
amplifier designed for broadband CATV distribution 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, 70 mA,
from a single 5V supply.
Specifically designed for cable, data, and video applications, the MT1110 features a
unique integrated equalization circuit that adds 0.5 dB of positive tilt to the gain
slope to compensate for a commonly occurring frequency dependent attenuation
found in broadband applications.
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 a SOT-89 package for the extended industrial
temperature range of -40°C to +85°C.
