31.75 dB Range / 0.25dB Step Digital VGA
0.05 to 8 GHz

The GRF6412 is a SPI-controlled, 31.75 dB range digital variable gain amplifier (DVGA) which provides precise stepping in 0.25 dB increments. The device’s serial interface utilizes three externally defined address bits, allowing up to 8 unique devices to share a common SPI bus. In addition to supporting traditional serial programming, the GRF6412 also includes a special Rapid Fire™ selection pin which allows the device to be immediately switched into a pre-defined attenuation state.

In terms of performance, the GRF6412 can cover the entire 50 MHz to 8 GHz range while still maintaining flat gain as well as precise and monotonic gain stepping. Glitching has been minimized to < 2 dB for all steps. The flexibility of the bi-directional attenuator also allows the device to support DSA+AMP as well as AMP+DSA cascaded configurations.
