DC - 35 GHz Wideband Amplifier
TGA4832
Product Description
The TriQuint TGA4832 is a medium power wideband
AGC amplifier which operates from DC to 35 GHz.
Typical small signal gain is 12dB and typical input and
output return losses are >10dB. The TGA4832
provides 18 dBm of output power at 1 dB gain
compression.

Drain bias may be applied through the output port for
best efficiency or through the on-chip drain termination.
Two stages in cascade demonstrate 3.8Vpp output
voltage swing with 350mV at the input when stimulated
with 40Gb/s 2^31-1prbs NRZ data. RF ports are DC
coupled enabling the user to customize system corner
frequencies. The TGA4832 requires off-chip
decoupling and blocking components.
The TGA4832 is suitable for a variety of wideband
electronic warfare systems such as radar warning
receivers, electronic counter measures, decoys, and
jammers. It is also an excellent choice for 40Gb/s NRZ
applications. The TGA4832 is capable of driving an
Electro-Absorptive optical Modulator (EAM) with
electrical Non-Return to Zero (NRZ) data. In addition,
the TGA4832 may also be used as a predriver or a
receive gain block.
Bond pad and backside metallization is gold plated for
compatibility with eutectic alloy attachment methods as
well as the thermocompression and thermosonic wire
bonding processes. Each device is 100% DC and RF
tested on-wafer to ensure performance compliance.
The device is available in die form.

1/ These ratings represent the maximum operable values for the device.
2/ Assure Vd - Vctrl 8 V. Compute Vd as follows, Vd = V+ - Id*40
3/ Combinations of supply voltage, supply current, input power, and output power shall not exceed PD.
4/ When operated at this power dissipation with a base plate temperature of 70°C, the median life is 1 E+6 hours.
5/ Assure Vctrl never exceeds Vd during bias up and down sequences. Also, assure Vctrl never exceeds
5V during normal operation.
6/ Junction operating temperature will directly affect the device median time to failure (MTTF). For
maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.
