TGA4802
12.5 Gb/s IRZ Modulator Driver
Qorvo's TGA4802 is a medium power wideband AGC amplifier MMIC die that is part of a series of optical driver amplifiers suitable for a variety of driver applications. The part typically provides 15 dB small signal gain with 10 dB AGC range. RF ports are DC coupled enabling the user to customize system corner frequencies.
The TGA4802 is an excellent choice for 12.5 Gb/s optical modulator driver applications. The TGA4802 has demonstrated the capability to amplify a 2 V input signal to 7 Vpp saturated.
The TGA4802 requires off-chip decoupling, a DC block and a bias tee. The TGA4802 is available in die form.
