12.5Gb/s Modulator Driver Amplifier
Metro and Long Haul Applications
TGA4802-EPU
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.
