... It is also useful for applications in 900 MHz, 2.4 GHz and 5.7 GHz ISM (Industrial-Scien- tific-Medical) bands requiring digi- tal modulation, such as Local Area Networks (LANs). The HPMX-2005 is fabricated with Hewlett-Packard’s 25 GHz ISOSAT-II process, which com- bines stepper lithography, self- alignment, ion-implantation techniques, and gold metallization ...

... All performance data shown on this data sheet was taken with unbalanced I/Q inputs. LO Input (pins 7 and 8) The LO input of the HPMX-2005 is balanced (differential) and matched For drive from a unbalanced LO, pin 7 should be AC coupled to the LO using a 50 transmission line and a blocking capacitor (1000 pF typ ...

... HPMX-2005 Typical Data Measurement Direct measurement of the ampli- tude and phase error at the output is the most accurate way to evalu- ate modulator performance. By measuring the error directly, all the harmonics, LO leakage, etc. that show up in the output signal are accounted for. Figure 3 below ...
