Text: Harris Semiconductor No. AN9641.1 Harris Linear April 1998 High-Frequency VGA Has Digital Control Author: Ronald Mancini Introduction You should keep the video input signal level at about 25mV to prevent distortion. The signal path has an excellent frequency response because the HFA3102 is the only component in the signal path. A frequency response plot for VB3 = 3V gain of 10dB shows that the transfer function is wellbehaved with no peaking and that the frequency response is

Abstract: HFA3102 HI5731
Text: High-Frequency VGA Has Digital Control TM Application Note April 1998 Introduction R2, R3, and the -5V supply form a bias circuit that sets VB3 to -4.4V when there is no DAC output current the voltage across R1 is zero , which occurs at a digital input of all ones.

Text: High-Frequency VGA Has Digital Control Application Note Introduction You can use variable-gain amplifiers VGAs in many types of systems, such as radio receivers, in which the input signal voltage depends on an uncontrolled variable, such as distance to the transmitter. In this type of system, you can
