Description
Primary Applications
• Mach-Zehnder Modulator Driver
• Pre-Driver
• Receiver AGC
The TriQuint TGA8652-SL is a medium power wideband
AGC amplifier combined with off chip circuitry assembled in
a Surface Mount Package. The TGA8652-SL typically
provides 16dB small signal gain with 6dB AGC range.
Typical input and output return loss is <10dB. Typical Noise
Figure is 2.5dB at 3GHz. Typical saturated output power is
25dBm. Small signal 3dB BW is 12GHz with saturated
power performance to 16GHz. RF ports are DC coupled
enabling the user to customize system corner frequencies.
Applications include OC192 12.5GBit/s NRZ MZ Modulator
Driver and receive AGC amplifier.
Measured Performance
Cascaded 8652 Evaluation Boards
12.5 Gb/s Performance
Output = 8 Vpp, Input = 500 mVpp
Scale: 2 V/div, 20 ps/div
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. A cascaded pair demonstrated
8Vpp output voltage swing with 500mVpp at the input when
stimulated with 10GBit/s. 2^31-1prbs. NRZ data.
The TGA8652-SL is available on an evaluation board.
