Ini adalah perintah utama untuk memberikan recever rF, dan untuk itu, kita harus melakukan sesuatu yang lebih baik.

Calculations for Noise Figure and Gain

Kalkulations indecive decive the noise figure (NF) and gain at each stape. Te Friik formula is communily usuad to estimate the overall noise figure:

11; Syari1; FLT: 0 AF3; NF _ total = NF1 + (NF2 - 1) / G1 + (NF3 - 1) / (G1 * G2) 1991; FLT: 1 MIL3;\ 323;

where NF is the noise factor (linear form), and G is the gain of ef stale. Propet millation ensures the first has ha th e lowest NF and sufficient gain to suppress acteren noise noise contributions.

Practichal Tips for Low- Noise Recever Design

  • 1f 1; FLT: 0 = 03. 03. Use high-quality components: lef1; FLT: 1: 1 ASA3; Selet low-noise amplifiser and resistors with minmal noise.
  • Pertama, FLT: 0 = 33. Impedance matching:
  • Pertama; FLT: 0 = 33. Shielding and grounding:
  • FLT: 0 = 33; Filtering: 501; FLT: 1; 123; Incorporates filters to eliminate out-of-band noise and signals.
  • Pertama, FLT: 0; 0 (3) Powir supply noise reduction: S01; FLT: 1 FLT: 1 AF3; Use filtering and regulation to prevent powir noise fromam afecting incive stades.
