TGA4801

TGA4801 DC – 35 GHz MPA with AGC Key Features and Performance 0.25um pHEMT Technology DC - 23GHz Linear BW DC - 35GHz Saturated Power BW 14dB Small Signal Gain 10ps Edge Rates (20/80) 7Vpp 43Gb/s NRZ PRBS Amplitude and Symmetry Control Chip Dimensions 3.3mm x 2.0mm Primary Applications: Description The TriQuint TGA4801 is a medium power wideband AGC amplifier that typically provides 10dB saturated midband gain with 6dB AGC range. Typical input and output return loss is >10dB. Typical Noise Figure is 2.5dB at 6GHz. Typical saturated output power is 24dBm at 20GHz. Small signal 3dB BW is 25GHz with saturated power performance to 35GHz. RF ports are DC coupled enabling the user to customize system corner frequencies. The TGA4801 is an excellent choice for 43Gb/s NRZ applications. The TGA4801 is capable of driving a Lithium Niobate Optical Modulator with electrical NonReturn-to-Zero (NRZ) data. Drain bias may be applied thru the output port for best efficiency or thru the on-chip drain termination. A cascade consisting of three TGA4803’s followed by a TGA4801 demonstrated greater than 7V(amplitude) output voltage swing with 350mV at the input when stimulated with 43GB/s 2^31-1 PRBS NRZ data. Output eye patterns shown to the right. The TGA4801 requires off-chip decoupling and blocking components. Each device is 100% DC and RF tested onwafer to ensure performance compliance. The device is available in chip form. Lead-free and RoHS compliant 26Gb/s NRZ 2^31-1 PRBS ...
