Focus Microwaves - Focus Compact Modeling Software

The Focus Compact Model (FCM) utility is a streamlined software package designed to be used with Focus’ AURIGA high-end Pulsed-IV system

Setup

Pulsed S-Parameter Setup

The purpose of electrical representation or equivalent circuit of HEMT or any transistor in the form of lumped circuit elements is to implement and simulate its static and RF behavior in CAD tools. This technique is particularly useful and often directly correlated to physical entities within the device structure, as illustrated below. 

The illustration below is a small signal topology composed of a total of 16 linear components. 

This is divided into two parts: 

i) The Intrinsic part where the region under the gate (modulation occurs here) represented with a set of 8 intrinsic elements (RGD, Ri, CGS, CGD, CDS, GM, RDS, Τ). 

ii) The Extrinsic part represented with a set of 8 extrinsic elements (RG, RD, RS, LG, LD, LS, CPG, CPD). These elements need to be extracted for small signal model implementation. The extraction process will be discussed in the following section.

More Product Information

Focus Microwaves

Focus Microwaves is a pioneering engineering company, built around the innovations of its founder Dr. Christos Tsironis who developed his first manual tuner in 1973 and is the inventor of most existing electro-mechanical tuner families. The success of Focus is based on the engineering and manufacturing skills of its highly motivated and experienced team of engineers and technicians, who have been trained and encouraged to develop new technologies. In addition, listening to our customers needs and insights helps us discover and develop new and measurement methods on an ongoing basis, relentlessly pushing the limits of what is possible. 

From humble beginnings in 1988, Focus has become the main supplier of advanced Load Pull and Noise Tuner Systems. Our mission is to provide effective, reliable and innovative solutions for non-50 Ohm testing (Noise and Load Pull) of RF microwave transistors, thus enabling our customers to compete in the marketplace with better designs and to advance the understanding and knowledge of the field.
