3 - 7 V Optical Modulator Driver
The TriQuint TGA4956-SM is a MZ and low voltage modulator driver amplifier designed to operate at frequencies that target the 10 Gb/s optical market using an economical 8 x 8 mm surface mount package.
The TGA4956-SM consists of two high performance wideband amplifiers combined with off-chip circuitry assembled in a surface mount package. A single TGA4956-SM placed between the MUX and Optical Modulator provides OEMs with a low-cost, surface mount modulator driver solution.
The TGA4956-SM provides Metro and Long Haul designers with scalable power dissipation for varying output drive requirements (less than 0.42 W at Vo = 3 Vpp, less than 1 W at Vo = 6 Vpp).
RoHS compliant, Moisture Sensitivity Level 1. Evaluation boards available upon request.
