Text of the note
Show as plain text (Turkish; formulas and drawings are not included)
Low Noise Figure olmalı.
Low power consumption
NF : Noise figure
oluşacak frekanslar: 2,1 ve 1,9
Osilatörler & VCO (Voltage controlled oscilator)
Frequency stability, phase Noise
kristal osilatörlerin beslemeye ihtiyacı
VCO gerilim kontrollü osilatör
TCXO (Temperature controlled Osc.)
sıcak kontrollü, geri besleme ile sıcaklık etkisini minimize eder
OCXO (Oven Controlled Osc.)
PLL (Phase Locked loop)
(Max) Output power
Power efficiency (PAE) Power added efficiency
F, E → High power efficiency
AM (Amplitude Modulation)
high Freq RF signal
Frequency Modulation (FM)
Non-Linearity Problems
Reflection, Transmission & matching
Amfiyi doyurmadan linear bölgede çalışması için
V_1^- ne kadar küçükse yansıma o kadar azdır
