The TriQuint TGA4942-SL is a single channel optical modulator driver amplifier designed for the 43 Gb/s optical market. The TGA4942-SL is a compact SMT using three high performance wideband amplifiers and an integrated broadband bias tee assembled in a 16 x 8 x 3.7 mm package, requiring a minimum of off-chip components. A single TGA4942-SL placed between the MUX and Optical Modulator provides OEMs with a modulator driver surface mount solution.

The TGA4942-SL provides Metro and Long Haul designers with system critical features such as: low power dissipation, high signal to noise ratio (SNR), high voltage drive capability (3 Vpp amplitude adjustable up to 8 Vpp), fast rise and fall times, low output jitter, and low input drive sensitivity (0.4 Vpp – 1 Vpp at Vout = 8Vpp).

The TGA4942-SL is RoHS compliant. Evaluation boards and bias boards are available upon request.
