Qorvo's TGA4826-SM is a high power wideband amplifier that is part of a series of optical driver amplifiers suitable for a variety of optical network applications. This part typically provides 22 dB small signal gain.
The TGA4826-SM is an excellent choice for applications requiring high drive combined with high linearity. The TGA4826-SM can be used as a gain block when Vdbypass is used, or alternatively, can deliver up to 10 Vpp when Vd is biased through an external bias tee through the RFout line.
The TGA4826-SM requires an RF choke, DC blocks and/or bias tees, if required, and control circuitry. The part is lead-free and RoHS compliant. MSL1 per IPC/JEDEC J-STD-020C. Evaluation boards available on request.
Typical Applications
- Mach-Zehnder Modulator Drivers
- Metro and Long Haul Optical Networks
