| Abstract: |
| The design of a low noise Ka-band receiver front-end used in satcom is
presented.Through appropriate choice of components and circuits form and optim
iziation of input port matching circuits，a low noise Ka-band
receiver front-end is realized. The frequency is at 30 GHz.In 0.8 GHz fr
equen
cy bandwidth,the NF(Noise Figure) is less than 2.2 dB,the gain is more than 60
dB and gain fluctuation is less than 1dB.
The test result of 3 sets of samples demonstrate the validity of design. |
