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....
