General Description
The TriQuint TGA4942-SL is a single channel optical
modulator driver amplifier designed for the 43 Gb/s optical
market. The TGA4942-SL is a compact SMT using three
high performance wideband amplifiers and an integrated
broadband bias tee assembled in a 16 x 8 x 3.7 mm
package, requiring a minimum of off-chip components.
A single TGA4942-SL placed between the MUX and
Optical Modulator provides OEMs with a modulator driver
surface mount solution.
The TGA4942-SL provides Metro and Long Haul
designers with system critical features such as: low power
dissipation, high signal to noise ratio (SNR), high voltage
drive capability (3 Vpp amplitude adjustable up to 8 Vpp),
fast rise and fall times, low output jitter, and low input drive
sensitivity (0.4 Vpp 1 Vpp at Vout = 8Vpp).
The TGA4942-SL is RoHS compliant. Evaluation boards
and bias boards are available upon request.
