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).
