MIXER PRODUCTS
MITEQ’s Special Mixer Products Department offers the industry’s smallest microstrip-compatible mixer covering the
specified frequency range from 4 to 18 GHz with performance operating to 20 GHz. The design achieves low RF input
VSWR, while also maintaining a strong solderable interface connection on 0.030 inch wide 1 1/2 ounce copper lines.
The deck to microstrip height of 0.039 inch (1 mm) is consistent with a very small ground ledge inductance for a supe-
rior microstrip interface. This device performs as an up- or downconverter.
