| Abstract: | The development results of a PHEMT monolithic low-noise amplifierfor X-band DBS use are described in this paper. The CAD method, including MBEmaterial, PHEMT device and monolithic circuit, has been discussed and the optimum design has been completed. The special technique in MMIC process has beendeveloped for LNA fabrication- Single-stage MMIC exhibits noise figure of lessthan 1. 8 dB wlth ga1n of more than 6. 8 dB in the frequency range of 11. 7 to 12. 2GHz. For dual stage MMIC, noise figure of less than 1. 96 dB with gain of morethan 15. 3 dB in the frequency range of 10. 4 t0 11.1 GHz is obtained. The minimum noise figure is 1. 63 dB and maximum gain is 16. 07 dB at 10. 4 GHz. |
