MODEL GB/S BROADBAND AMPLIFIER

Transcription

1 Electro-Absorption Modulator driver or optical receiver amplifier khz - 43 GHz bandwidth 8 ps risetime.7 V amp eye amplitude 8.5 db gain MODEL GB/S BROADBAND AMPLIFIER The 5881 is extremely broadband, covering over 6 decades from khz to 43 GHz. It also demonstrates a very clean time domain response, resulting in high quality 4 Gb/s eye diagrams. The 5881 includes internal reverse voltage protection, power supply regulation, and sequencing circuitry, making it insensitive to power supply voltage variation and application sequence.
