The TriQuint TGA4947-SL is a dual channel optical modulator driver amplifier designed to operate at frequencies that target both the 40 and 100 Gb/s optical markets using a 16 x 10.5 x 3.6 mm surface mount system in package (SIP).   

The TGA4947-SL consists of two channels of three high performance wideband amplifiers and integrated broadband bias tees assembled in a surface mount package, requiring a minimum of off-chip components.  A single TGA4947-SL placed between the MUX and Optical Modulator provides OEMs with a modulator driver surface mount solution.

The TGA4947-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 9 Vpp), fast rise and fall times, low output jitter, and low input drive sensitivity (0.4 Vpp – 1 Vpp at Vout = 8Vpp).
