Active Components

ComponentPortsKey parametersNotes
Low Noise AmplifierIN, OUTGain, Noise Figure, IIP3, Input P1dB, Freq Min/MaxFirst gain stage in RX; NF dominates cascade
Power AmplifierIN, OUTGain, Noise Figure, Input P1dB, Output Psat, EfficiencyFinal stage in TX; linearity critical
DriverIN, OUTGain, Noise Figure, Input P1dB, Output PsatPre-PA stage
AmplifierIN, OUTGain, Noise Figure, IIP3, Input P1dBGeneric gain stage
Variable Gain AmplifierIN, OUTGain, Noise Figure, IIP3, Input P1dBVariable gain; set Gain to operating point
BufferIN, OUTGain, Noise FigureTypically unity gain; provides isolation
MixerRF, LO, IFGain (conversion), Noise Figure, IIP3, IIP2, LO Frequency, LO PowerNegative gain = conversion loss

Passive Components

ComponentPortsKey parametersNotes
Bandpass FilterIN, OUTGain (loss), Center Frequency, Bandwidth, Freq Min/MaxEnter gain as negative
Highpass FilterIN, OUTGain (loss), Freq Min/Max
Lowpass FilterIN, OUTGain (loss), Freq Min/Max
Bandstop FilterIN, OUTGain (loss), Center Frequency, Bandwidth
AttenuatorIN, OUTGain (loss)Fixed pad; enter as negative

Boundary Components

ComponentPortsKey parametersNotes
DACOUTOutput PowerTX chain source; Output Power seeds cascade
ADCINMax InputRX chain endpoint
Signal SourceOUTOutput PowerGeneric RF source
AntennaRFRF boundary used as either input or output depending on operating mode
OutputINChain endpoint marker

Support Components

ComponentPortsKey parametersNotes
Local OscillatorOUTLO Frequency, LO Power, Phase NoiseExcluded from cascade; connects to mixer LO port only

Port compatibility rules

Valid connections:

  • OUTIN
  • in TX mode, the main path enters the mixer on IF and exits on RF
  • in RX mode, the main path enters the mixer on RF and exits on IF
  • OUTLO (LO block to mixer LO port)

Invalid connections:

  • ININ
  • OUTOUT
  • Connecting to a boundary block's output-only port
