Analog Devices LTC6412 Variable Gain Amplifier Application Note
The document introduces the LTC6412, Linear Technology's first high-frequency, analog-controlled Variable Gain Amplifier (VGA). It highlights the device's use in communications and imaging applications such as cellular radio, satellite receivers, radar, and ultrasound. The text compares analog versus digital control methods for VGAs, noting that while digital is common, analog solutions are necessary when system parameters are unknown or RF signals cannot tolerate step disturbances.
