XC2402KT69UR-G
UHF Band Low Noise Amplifier
ETR27003-004a
■GENERAL
DESCRIPTION
The XC2402KT69UR-G is an ultra-low-noise amplifier (LNA) with low operating voltage, low nose figure (NF), low power
consumption using CMOS process. The XC2402 is designed for 470MHz½880MHz bandwidths of terrestrial digital TV.
The device offers easy output matching to 50Ω for input and output with less external components.
With external control mode, High Gain mode can be selected by passing through the amplifier circuit and Low Gain mode
can be selected by bypassing the amplifier circuit. Low Gain mode in environments with good radio wave conditions to help
save system energy.
