RF Active Devices
RF Active Devices
Design tools for RF amplifiers, oscillators and mixers — PA efficiency and class comparison, transistor bias networks, VCO phase noise estimation, mixer spur analysis, AGC range calculator and LNA noise match designer.
PA Efficiency Calculator
Compare Class A/AB/B/C/D/E/F efficiencies. Conduction angle, Pout, PAE, harmonic content and class comparison table.
Transistor Bias Designer
BJT voltage divider, FET self-bias and active bias networks. Resistor values, stability factor S, bypass cap specs.
VCO & Oscillator Design
Leeson equation phase noise estimator, tank circuit design, tuning sensitivity, Colpitts/Hartley topology.
Mixer Design Calculator
IF/image frequency, spur table, conversion gain, IIP3, DSB/SSB noise figure, LO power and port isolation specs.
AGC / VGA Calculator
Gain control range, control law (linear/log), dynamic range, NF vs gain, settling time and VGA control voltage.
LNA Noise Match Designer
Noise vs gain trade-off. Enter F_min, Rn, Γ_opt — get NF, available gain, matching network component values.
