At a Glance
- Impedance conversion: 25 Ω↔50 Ω, Ultra-broadband operation more than 67 GHz
Technical Background
Ultra broad-band impedance conversion IC is used to characterize RF components in both time- and frequency-domain, which does not have 50 Ω impedance (25 Ω). It shows more than 67 GHz bandwidth and provides integrated DC supply pads. It suits for the characterization of Mach-Zehnder modualtor driver IC since it has either open-collector or the output impedance of 2 x 25 Ω.
Features
- Differential input 50 Ω and differential output 100 Ω
- Integrated DC supply pad
- Supports data rates more than 32 GBd
- RF input pads for double wire-bondings
Applications
- Characterization of Mach-Zehnder modulator driver
- Ultra-broadband impedance conversion
