Models: New RF Additions

RF switches

Single Pole n-Throw and Double Pole Double-Throw

P1dB and IP3 parameters

Static and Dynamic

RF digital and RF analog phase shifter

Digital phase shifter use digital control word and analog use a real

control signal Static and Dynamic

RF delay blocks

Adds appropriate frequency dependent phase shift to signal Static and Dynamic

Variable Digital Step Attenuator

Variable Voltage Attenuator (VVA)

RF Combiner Supports impedance mismatch

Voltage vs. Power combining

Center frequency is now back propagated

RF splitter

Supports real and complex signals

Two input, two output Quad Hybrid

Supports real and complex signals

Measurements: RF Budget (RFB)

RFB

C_IPHS_NOISE cascaded integrated phase noise

C_PHS_NOISE cascaded phase noise

C_S11 cascaded input reflection

C_S22 cascaded output reflection

G_T G/T (gain to system temperature ratio) Tsys system equivalent noise temperature

Typical Satellite Communication measurements


9/14


Measurements: RF link


10/14


Measurements: Related

RFB measurements C_TE and C_TN now use the

equations instead of basing their results on NF.

Allows input noise temperature to be any value.

Passive components can have temperature parameter


11/14


RFB noise simulations now take into account

compression for amplifiers and mixers

You can now have multiple RF Inspector windows at

once and continue to work in AWRDE with the windows

open

An improvement in how AMP_B handles gain when driven

into saturation has been added

Mixer_S bug fixed

P1dB, IP3, and gain conversion now extracted correctly
