Primary Applications
• Mach-Zehnder Modulator Driver for Metro and Long Haul

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.

Notes:
1/ These ratings represent the maximum operable values for the device.
2/ Assure the combination of Vd and Id does not exceed maximum power dissipation rating.
3/ Assure Vctrl never exceeds Vd during bias on and off sequences, and normal operation.
4/ When operated at this bias condition with a base plate temperature of 700C, the median life is reduced.
5/ Junction operating temperature will directly affect the device median time to failure (MTTF). For
maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.
6/ These ratings apply to each individual FET.
