Amplifier design without the guesswork
Amplifier design and impedance-matching software (the IMW is a subset of the ADW). Small-signal, low-noise, power, high efficiency, as well as high dynamic range amplifiers can be designed.
V10.4 (Build 7474) has been released. The harmonic control features in the Impedance-Matching Module, as well as CIL Wizard were enhanced in this version. Point matches, as well as circle matches are now allowed when the power contour option is selected. When the intrinsic load line option is selected, the harmonic terminations (2nd and/or 3rd harmonics) can now also be controlled. This can currently be done for class-A, class-B, Class-F, continuous class-F and continuous inverse class-F stages. The harmonic terminations specifications are also entered automatically in the .hrm file required for harmonic control by the Impedance-Matching Module.
Two design flows are provided in the ADW:
The parameters of the discontinuity models used in the ADW can be optimized to allow for easy adjustment of the network to provide the EM performance required. Only two EM simulations are usually required. The first simulation is used to adjust the parameters of the discontinuity models, after which it is re-optimized in the ADW and the second is used to verify that the performance is as required. Note that it may be necessary to reduce large steps in line width by introducing extra intermediate steps (tapering).
systematic approach is then followed to
design each stage of the amplifier, after
which the completed design is optimized. The
amplifier is then exported for fine-tuning
and further processing.
