Applied Cavity Perturbation Used for Frequency Identification of Channel Ports in Manifold-Coupled Multiplexers

Table 1

A comparison between recent deembedding techniques proposed for filters in a multiplexer.

Technique	Validation	Features	Reference
Computing a rational model	Theoretically	High accuracy	[2, 12, 21]
		Stability not guaranteed
		Junction prior knowledge not required
Recursive Schur’s algorithm	Theoretically	Assuming a lossless system	[22]
		Limited to diplexers
Polynomial approximation	Theoretically	Quick and accurate	[17]
		Simple implementation
This work	Practically	Reasonable accuracy
		No prior knowledge required
