1 / 9 page 1 TGA4803 May 2009 © Rev - Description The TriQuint TGA4803 is a medium power wideband AGC amplifier that typically provides 8dB small signal gain with 3dB AGC range. Typical input and output return loss is >10dB. Typical Noise Figure is 5dB at 3GHz. Typical saturated output power is 17dBm. Small signal 3dB BW is >50GHz. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4803 is an excellent choice for 43Gb/s NRZ applications. The TGA4803 is capable of driving a single Electro-Absorptive optical Modulator (EAM) with electrical Non-Return to Zero (NRZ) data. In addition, the TGA4803 may also be used as a transmit predriver or a receive gain block. Drain bias may be applied through the output port for best efficiency or through the on-chip drain termination. Three stages in cascade demonstrated 3.8Vpp output voltage swing with 350mV at the input when stimulated with 43Gb/s 2^31-1prbs NRZ data. The TGA4803 requires off-chip decoupling and blocking components. Each device is 100% DC and RF tested on-wafer to ensure performance compliance. The device is available in die form.
