matchedRF app for iPhone and iPad

matchedRF is a network synthesis tool for broadband RF applications. It supports impedance matching for a restricted class of terminations - namely the capacitive sources and loads that are so commonly encountered during the design phase of RF power amplifiers.

Since filter structures are the most efficient broadband impedance-matching structures, matchedRF outputs filter-based lumped LC ladder structures that are matched to user specifications at both ends of the network. The tool is helpful in that the parasitic capacitance of an active device can be absorbed by the matching components at either end of the network or even both ends simultaneously. matchedRF is directly applicable to input matching, output matching and interstage matching in the design of broadband RFIC and millimeter wave power amplifier systems.

Wherever possible, matchedRF generates the Fano-Optimum, lumped-element Chebyshev filter structure representation.

Bandpass topologies of network order 2 through 6 are supported.

In addition, the tool supports the recommendation, insertion and manipulation of lumped-element impedance transformers. matchedRF provides the transformer solutions (if they exist) and allows users to further add or remove transformers and make refinements such that component values closely match those supported by their manufacturing process.

matchedRF plots the frequency response of:
- insertion loss
- return loss
- transmission phase
- group delay
