General Description

The MAX2065 high-linearity, analog/digital variable gain amplifier (VGA) is designed to operate in the 50MHz to 1000MHz frequency range with two independent attenuators (see the Typical Application Circuit). The digital attenuator is controlled as a slave peripheral using either the SPI?-compatible interface or a parallel bus with 31dB total adjustment range in 1dB steps. An added feature allows “rapid-fire” gain selection between each of four steps, preprogrammed by the user through the SPI-compatible interface. The 2-pin control allows the user to quickly access any one of four customized attenuation states without reprogramming the SPI bus. The analog attenuator is controlled using an external voltage or through the SPI-compatible interface using an on-chip 8-bit DAC.
