The TriQuint TGA4943-SL is a three stage optical modulator driver amplifier designed to operate at frequencies that target both the 40 and 100 Gb/s optical market using an 14.4 x 7 x 2 mm surface mount system in package (SIP).

The TGA4943-SL consists of three high performance wideband amplifiers assembled in a surface mount package combined with a minimum of off-chip components. A single TGA4943-SL placed between the MUX and Optical Modulator provides OEMs with a modulator driver surface mount solution.

The TGA4943-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, low rail ripple, high voltage drive capability (3 Vpp amplitude adjustable up to 9 Vpp), low output jitter and low input drive sensitivity (0.4 Vpp to 1 Vpp at Vout = 8Vpp). The part is lead-free and RoHS compliant. Evaluation boards are available upon request.
