I'm currently doing a project on LNA(low noise amplifier) for my final year. Any help or suggestion on design and its improvement is useful for my project.
Hope this becomes a forum of discussion on design of Low noise Amplifier for C band
Specs:
1. Frequency: 3625 to 4800 MHz
2. Noise Figure: less than 3dB
3. S22 : good output return loss
4. S11: good input return loss
5. Noise temperature: 60 deg. K max. (Including LNA & Switching)
6. Gain: 60 dB min.
7. Gain flatness over the band: ± 1.5 dB
8. Gain stability over Temperature: ± 1.5 dB over the band 0.40 dB p-p over 40 MHz
9. Input VSWR: 1.30 : 1
10. Output VSWR: 1.30 : 1
11. I/P interface: WR 229 CPR (G), (Standard feed interface dimensions)
12. O/P interface: N-type (female) connector
13. Group delay: 0.02 ns / MHz max. Linear
0.003 ns / MHz Sq. Max. Parabolic
0.3 ns peak to peak max. Ripple
14. Max. Input Power without damage: 0 dBm
15. Power Output: (@ 1-dB Gain Compression) +10 dBm Min.
16. Output Third Order Intercept (OIP3): + 20 dBm Min.
17. Temperature Range: 0 to +60 °C
18. Reliability MTBF: 48000 hours or better
19. Power Consumption: optimized power consumption
