<Text 340 480 12 #ff0000 0 "Two sets of simulation functions are used - SP1 and Opt1 is to optimize the cavity and coupling dimensions and SP2 and Opt2 is to normalize the phase over the\n10 MHz information passband (using a negative length of 50 ohm transmission line) to determine the maximum deviation from linear phase (which is+/- 0.3 deg).\n\nTransmission line Z1 represents a coupling wire between tapped co-axial resonators at L=2e-2 from ground and approximately .800 inches long (distance between\nresonators). C3 = input and output voltage probes at location defined by the intersection of L1 and L2. C1 are tuning screws at the ends of resonators.\n\nTo optimize physical dimensions, deactivate Eqn2, Opt2, SP2 and replace the length of Line8 with any number, "0.1" will do. SP1 and Opt1 should be activated. If\nthe optimized dimensions are satisfactory, replace the variables in Eqn2 with them and activate Eqn2. To evaluate phase linearity, deactivate Opt1 and SP1. Activate\nOpt2 and SP2 then replace the length of Line8 with variable "L4". The optimizer (Opt2) will optimize the negative length of the 50 ohm line required to normalize phase\ndeviation so that the actual value is displayed.\n\nNOTE: optimization and phase normalization can be accomplished in a simpler manner but most applications do not require phase linearity hence separate processes.">
