Ampsa provides its customers with a structured amplifier design process for robust high performance RF and microwave amplifiers. Get started with the powerful Impedance-Matching Wizard (IMW) and then upgrade to the Amplifier Design Wizard (ADW). Harmonic control features are provided in both wizards for maximizing the efficiency of linear power amplifiers. Training can be provided on the software, as well as amplifier design in general and the wizards can be customized to improve the design flow.


Amplifier Design

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.

Two design flows are provided in the ADW:

 1.       You can do all the active work including defining the specifications for the matching problems to be solved in Microwave Office (TM) or the Advanced Design System (TM) and only design the matching networks (with or without harmonic control) with the Ampsa Wizards. A complete flow is provided for this in the ADW from synthesis, to fine tuning and introducing modifications in the matching network for biasing purposes, reducing discontinuity effects or replacing basic components with alternatives (inductor to spiral inductor or solenoidal coil, etc.) to re-optimizing the matching network to restore its performance after the modifications made. The final matching network can be exported in various formats, including DXF, Sonnet Software (R) format and also as a Microwave Office (TM) script.

 2.       When linear cascade-type amplifiers are designed most of the work can be done in the ADW with linear models and boundary-line constraints on the I/V-plane, after which the designed amplifier can be exported for fine-tuning with non-linear models and further processing. The ADW design process usually starts with fitting linear ADW models to the class A or B S-parameters of the transistors to be used at the required dc operating points (the operating point corresponding to the rated output power) and specifying the associated I/V-plane information. A 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.
