| Abstract: | In this paper, a kind of miniature amplifier module with low noise and high selectivity is introduced. This module of distributed parameters used in the lower microwave band is skillfully combined with an ultra-fine thin-film technology. Base on the design of the low-noise amplifier, the micro-strip BPF and the post balanced amplifier, this module is fabricated on 76 × 20 × 0. 5mm^3 Al2 O3 ceramic chip. The module works at the frequency band from 1.8GHz to 2. 2GHz with gain≥50dB, noise figure≤0. 9dB, output power （at ldB）≈30dBm, out band rejection≥80dB. |
