6431-20
50Ω gain block IF amplifier. The LTC6431-20 has a power
gain of 20.8dB and it is part of the LTC6431-YY amplifier
series.
The DC2077A demo board supports the LTC6431-YY am-
plifier family. The DC2077A demo board is optimized for
a frequency range from 100MHz to 1200MHz. It incorpo-
rates a minimum of passive components to configure the
