RF-MMIC Design

RF and MMIC Design with extensive experience

We at LNAFIN Oy have done a lot of design work at different microwave frequencies. Before microwave design work, we have done many RF and even baseband ASIC designs. As a result, the MMIC design workflow we use is fluent. We have included pictures above the page title to show a couple of examples of our past work in the field. These pictures show a 40-GHz 2.92-mm connector test PCB on the left, and a complementary bipolar SiGe IC on the right.

The 2.92-mm connectors in the leftmost picture are called K-connectors in the US. Presently we use Microwave Office for such planar design tasks, and FEM or a time-domain EM-simulator for the  3D electromagnetic simulations. In comparison, the MMIC on the right has been designed using the well-known IC design package Virtuoso etc. from Cadence. Our staff member has had a supervisor and co-designer role in the project.

2.5D / 3D EM-Modeling Solutions

In addition, we have a lot of experience of EM-modeling and testing planar RF circuit structures such as the RF-PCB shown (left). Thus we routinely apply electromagnetic simulation (EM simulation) tools to model different planar and 3D structures. We have included pictures of typical modeling situtations on this web-page. For example the two-part picture above shows one case, where we have imported circuit board manufacturing data. These are typically in gerber-format. After successful import of the data, we have modeled the board at microwave frequencies. This we did by application of a planar a EM-simulation tool to the purpose. In this particular instance, the simulator has been Keysight Momentum. After simulation, we have extracted useful data such as: s-parameter vector files (Touchstone), extracted RLC-element models, near-field and far-field graphics.
