Product Data Sheet August 5, 2008 12.5Gb/s Modulator Driver Amplifier Metro and Long Haul Applications TGA4802 Key Features and Performance Frequency Range: DC - 25 GHz Single-ended Input / Output 15 dB Small Signal Gain 18 GHz Small Signal Bandwidth Wide Drive Range (3V to 7V) 15ps Edge Rates (20/80) Power Dissipation 1.2 Watts 0.25um pHEMT 2MI Technology Die Size: 3.3 x 2.0 x 0.1 mm (0.131 x 0.79 x 0.004 inches) Description The TriQuint TGA4802 is part of a series of optical driver amplifiers suitable for a variety of driver applications. The TGA4802 is a medium power wideband AGC amplifier MMIC die that typically provides 15dB small signal gain with 10dB AGC range. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4802 is an excellent choice for 12.5Gb/s optical modulator driver applications. The TGA4802 has demonstrated capability to amplify a 2V input signal to 7Vpp saturated. The TGA4802 requires off-chip decoupling, a DC block and a bias tee. The TGA4802 is available in die form.
