General Description
The TriQuint TGA4894-SL is a dual channel optical
modulator linear driver amplifier designed for 100 Gb/s
optical markets.
The TGA4894-SL consists of two channels of high
performance wideband amplifiers and integrated
broadband RF Chokes assembled in a 16.1 x 10.6 x
3.6 mm package, requiring a minimum of off-chip
components. Two TGA4894-SLs placed between the
MUX and Optical Modulator provides OEMs with a
modulator linear driver surface mount solution.
The TGA4894-SL is lead-free and RoHS compliant.
Evaluation boards and bias boards are available upon
request.
