Product Description
The TriQuint TGA1171-SCC is a two-stage
PA MMIC design using TriQuint’s proven 0.25
µm
Power pHEMT process to support a
variety of millimeter wave applications
including point-to-point digital radio and point-
to-multipoint systems.
The balanced design consists of four 400
µm
input devices driving eight 400
µm
output
devices.
The TGA1171 provides 29 dBm of output
power at 1 dB gain compression and >30
dBm saturated output power across 36-40
GHz with a typical small signal gain of 14 dB.
Typical Input/Output RL is typically greater
than 12-15 dB across the band.
The TGA1171 requires minimal off-chip
components. Each device is 100% DC and
RF tested on-wafer to ensure performance
compliance. The device is available in chip
form.
