17-27GHz Variable Gain Amplifier
Note:
CHA4693-QGG
To decrease Noise or OIP3 variation versus gain control, it is possible to bias
separately the 3 gain control voltages, Gc1, Gc2, Gc3.
To limit Noise figure variation, keep Gc1 at -2V
To limit OIP3 variation, keep Gc3 at -2V
Output Power at 1dB Gain Compression versus Frequency and Temperature for GcX=-2V
