| Abstract: | The CAD of ultra-wide band low noise amplifier is described, andsome methods and critical techniques of achieving ultra-wide band low noise amplifiers by using common microstrip hybrid integrated circuit technology are also presented. Using the packaged BJTs and FETs separately, we have completed two ultra-wide band low noise amplifiers. The measured results fit with the design resultswell. One three-stage amplifier by using 2SC3358 presents gain G=20±1 dB andnoise figure NF≤3. 5 dB in frequency band from 30 kHz to 1 600 MHz. Anothertwo-stage amplifier with ATF 10235 (6) as the active devices gives gain G= 20±2dB and noise figure NF≤2 dB in frequency band from 500 kHz to 6 000 MHz. |
