... Application Information The HFA3101 array is a very versatile RF Building block. It has been carefully laid out to improve its matching properties, bringing the distortion due to area mismatches, thermal distribution, betas and ohmic resistances to a minimum. The cell is equivalent to two differential stages built as two “ ...

The addition of the resistors R 22 the dynamic range of the up converter as demonstrated at Figure 13. The evaluation results depicted in Table 5 have been obtained by a triple stub tuner as a matching network for the output due to the layout constraints ...

... Design Example: Up Converter Mixer Figure 12 shows an example converter for cellular applications. Conclusion The HFA3101 offers the designer a number of choices and different applications as a powerful RF building block. Although isolation is degraded from the theoretical results for the cell due to the unbalanced, nondifferential input schemes ...
