Description
The TriQuintwww.DataSheet4U.com TGA4819-SL is part of a series
of optical driver amplifiers suitable for a
variety of driver applications.
The TGA4819-SL is a medium power
wideband AGC amplifier that typically
provides 20dB small signal gain with 20dB
AGC range.
The TGA4819-SL is an excellent choice for
applications requiring high drive combined
with high linearity. The TGA4819-SL has
demonstrated capability to deliver 10Vpp
while maintaining output harmonic levels
near -30dBc for a 2GHz fundamental.
The TGA4819-SL requires a low frequency
choke and control circuitry.
Primary Applications
• Mach-Zehnder Linear Modulator Driver
for Metro and Long Haul
Preliminary Measured Performance
Bias Conditions: VD = 8V, VCTRL = +1V, ID = 310mA
PRBS 231-1; 10.7Gbps; Vin = 1Vpp; CPC = 50%
Note: This device is early in the characterization process prior to finalizing all electrical specifications. Specifications are subject to
change without notice.

1/ These ratings represent the maximum operable values for this device
2/ Combinations of supply voltage, supply current, input power, and output power shall not
exceed PD at a package base temperature of 70°C
3/ When operated at this bias condition with a baseplate temperature of 70°C, the MTTF is
reduced to 1.0E+6 hours
4/ 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.
