Product Description
The TriQuint TGA4943-SL is a three stage optical
modulator driver amplifier designed to operate at
frequencies that target the 28 Gb/s optical market
using an 14.4 x 7 x 2 mm surface mount system in
package (SIP).
The TGA4943-SL consists of three high
performance wideband amplifiers assembled in a
surface mount package combined with a minimum
of off-chip components. A single TGA4943-SL
placed between the MUX and Optical Modulator
provides OEMs with a modulator driver surface
mount solution.
The TGA4943-SL provides Metro and Long Haul
designers with system critical features such as:
low power dissipation, low rail ripple, high voltage
drive capability (3 Vpp amplitude adjustable up to 9
Vpp), low output jitter, and low input drive
sensitivity (0.4 Vpp – 1 Vpp at Vout = 8Vpp).
The TGA4943-SL is lead-free and RoHS
compliant. Evaluation boards are available upon
request.
