2 - 20 GHz Power Amplifier
Description
The TriQuint TGA8334-SCC is a GaAs monolithic dual-gate distributed amplifier.
Small-signal gain is typically 8 dB with positive gain slope across the band. Input
and output return loss is typically greater than 9.7 dB. Five 600um gatewidth FETs
provide more than 26 dB output power at 1 dB gain compression at midband.
Ground is provided to the circuitry through vias to the backside metallization.
The TGA8334-SCC is directly cascadable with other broadband TriQuint GaAs
amplifiers, such as the TGA8300-SCC, TGA8622-SCC, and TGA8220-SCC. This
general power amplifier is suitable for a variety or wide-band applications such as
distributed networks, logging stages and oscillator buffers.
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. The TGA8334-SCC is supplied in chip form and is readily
assembled using automated equipment.

... Product Application Note Recommended Maximum Input Power for TGA8334-SCC MMIC Background: TriQuint Semiconductor Texas has conducted tests to determine the maximum input power that can be applied to MESFET MMICs. In many applications, devices may be subjected to higher input powers than the recommended normal operating conditions understood that applications at greater than recommended input power may lead to degradation of device performance ...

Page 12

... An acceptable operating condition for input power is defined as a change of <10 change of <1dB in gain Table 1 illustrates that the TGA8334 devices are capable of handling 27dBm input signals for extended periods with only small degradation to RF and DC performance parameters. The mean value for catastrophic failure is near 39dBm ...
