TGA4803

The TriQuint TGA4803 is a medium power wideband AGC amplifier that typically provides 8 dB small signal gain with 3 dB AGC range. Typical input and output return loss is > 10dB. Typical Noise Figure is 5 dB at 3 GHz. Typical saturated output power is 17 dBm. Small signal 3 dB BW is > 50 GHz. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4803 is an excellent choice for 43 Gb/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 pre-driver 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 3.8 Vpp output voltage swing with 350 mV at the input when stimulated with 43 Gb/s 2^31-1 PRBS 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 and is lead-free and RoHS compliant.
