TLW also contains a powerful tuner modeling tool, allowing for the quick
design of hi-pass-L, lo-pass-L, and T networks. Once the complex line input
Z is calculated by TLW, the result can be input into the tuner model to
transform the complex Z into 50+j0.
For T network designs, TLW can compute C-L-C values based on desired phase
shift through the network for use with phased antenna systems. It's worked
so well that I can dial-in component values with a LCR analyzer, insert the
network into the transmission line and not require further adjustment.
