The Qorvo TGA4898-SL is a quad channel, differential input, differential output, optical quad limiting driver amplifier designed for 100 Gb/s optical markets.

The TGA4898-SL consists of four channels of high performance wideband amplifiers, input DC blocks and integrated broadband RF Chokes requiring a minimum of off-chip components. The TGA4898-SL has more than 25 dB of channel-to-channel isolation and 4 Vppd output amplitude.

The TGA4898-SL operates with one to three positive power supplies; no negative supply is required. For 4 Vppd output amplitude, the power consumption is less than 0.8 W per channel. The TGA4898-SL also has an internal output power detector for output control.

The TGA4898-SL is RoHS compliant. Evaluation boards and bias boards are available upon request.
