11. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers
Sammanfattning : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. LÄS MER
