... Cellular and Japan Digital Cellu- lar. It can also be used in digital transmitters operating in the 900 MHz ISM (Industrial-Scien- tific-Medical) band, including use in Local Area Networks (LANs). The HPMX-2003 is fabricated with Hewlett-Packard’s 25 GHz ISOSAT-II process, which combines stepper lithography, ion-implantation, self-alignment techniques, and gold metallization ...

... HPMX-2003 Typical Data Measurement Direct measurement of the ampli- tude and phase error at the output is an accurate way to evaluate modulator performance. By mea- suring the error directly, all the harmonics, LO leakage, etc. that show up in the output signal are accounted for. Figure 3, below, ...
