Primary Applications
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.
Lead-free and RoHS compliant
