MAX2063 Datasheet | Maxim Integrated

Description The MAX2063 high-linearity, dual digital variable-gain amplifier (VGA) operates in the 50MHz to 1000MHz frequency range. Each digital attenuator is controlled as a slave peripheral using either the SPI-patible interface or a 5-bit parallel bus with 31d B total adjustment range in 1d B steps. An added feature allows “rapid-fire” gain selection between each of four steps, preprogrammed by the user through the SPI-patible interface. A separate 2-pin control allows the user to quickly access any one of four customized attenuation states without reprogramming the SPI bus. Since each of the stages has its own external RF input and RF output, this ponent can be configured to either optimize noise figure (amplifier configured first) or OIP3 (amplifier configured last). The device’s performance features include 24d B of amplifier gain (amplifier only), 5.6d B noise figure (NF)...
