DC - 35 GHz Wideband Amplifier

Part # TGA4852


Key Features

  • 40 & 100Gb/s optical modulator driver
  • 0.15um power pHEMT technology
  • On-chip power detector
  • Bias: Vd = 6 V, Id = 170 mA
  • Chip size: 1.80 x 1.00 x 0.1 mm


The Qorvo TGA4852 is a medium power wideband AGC MMIC. Drain bias may be applied through the output port for best efficiency or through the on-chip drain termination. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4852 requires off-chip decoupling and blocking components.

The TGA4852 is an excellent choice for 40Gb/s and 100Gb/s applications. The TGA4852 is capable of driving a modulator with an adjustable output voltage of 3-10 Vpp. Bond pad and backside metallization is gold plated for compatibility with eutectic alloy attachment methods as well as the thermocompression and thermosonic wire bonding processes. Each device is 100% DC and RF tested on-wafer to ensure performance compliance. The device is available in die form.

Lead Free & RoHS Compliant.
