Description

The TriQuint TGA1328-SCC is a medium power

wideband AGC amplifier that typically provides 12dB

saturated gain with 6dB AGC range. Typical input and

output return loss is >10dB. Typical Noise Figure is

2.5dB at 3GHz. Minimum saturated output power is

25dBm. Small signal BW is near 14GHz with saturated

power performance to 18GHz. RF ports are DC coupled

enabling the user to customize system corner

frequencies.

The TGA1328-SCC is an excellent choice for 9.9, 10.7,

and 12.5Gb/s NRZ applications driving a Lithium Niobate

Optical Modulator with electrical Non-Return-to-Zero

(NRZ) data. In addition it may be used as a receive AGC

amplifier.

Drain bias may be applied thru the on-chip drain

termination resistor for low drive applications or thru the

RF output port for high drive applications.

The TGA1328-SCC requires off-chip decoupling and

blocking components. Each device is 100% DC and RF

tested on-wafer to ensure performance compliance.

The TGA1328SCC is available in chip form or assembled

into a surface mount package (see the TGA8652-EPU

data sheet for more information on the SMT package).
