iT5025

iT5025 40-Gb/s, 8-Vpp Optical Modulator Driver Description The iT5025 is a broadband GaAs MMIC traveling wave amplifier that delivers high output power and moderate gain from 30 kHz to 40 GHz. It is well suited for use as a generalpurpose, extremely broadband driver in OC-768 40 Gb/s optical communication systems, as well as any broadband application requiring flat gain response and excellent port matches. Seven P-HEMT cascode stages provide 8 Vpp output voltage to drive a LiNbO3 external modulator. The iT5025 incorporates advanced MBE technology, Ti-Pt-Au gate metallization, silicon nitride passivation, and polyimide for scratch protection. Low-frequency extension capabilities are also provided. www.DataSheet4U.com Features Frequency range: 30 kHz to 40 GHz Gain: 10 dB Gain flatness: ±0.7 dB Output voltage: 8 Vpp P1dB at 20 GHz: +21 dBm Psat at 20 GHz: +23 dBm Return loss Input: –12 dB Output: –10 dB Low-frequency operation Available in die form Absolute Maximum Ratings Symbol Vdd Idd Vg1 Vg2 PDC Pin Tch Tcase Tmax Parameters/conditions Positive drain voltage Total drain current First gate voltage Second gate voltage DC power dissipation RF input power Operating channel temperature Operating case temperature Maximum assembly temperature Min.
