Product Description
Primary Applications
• Point-to-Point Radio
• Point-to-Multipoint Communications
• K Band Sat-Com
The TriQuint TGA1135B-SCC is a balanced two-
stage HPA MMIC design using TriQuint’s proven
0.25 um Power pHEMT process. The
TGA11135B is designed to support a variety of
millimeter wave applications including point-to-
point digital radio and LMDS/LMCS.
The balanced configuration two stage design
consists of a pair of 600 um input devices driving
a 4 x 600um output stage. Power combining is
achieved with on-chip Lange couplers.
The TGA1135B-SCC provides 29 dBm nominal
output power at 1dB compression across
18 - 27GHz. Typical small signal gain is 14 dB
across the band. Input and output return loss is
typically -15dB.
An on-chip power detector and reference diode
may be used for power monitoring/control and
bias control loops.
The TGA1135B-SCC requires minimum off-chip
components. Each device is 100% DC and RF
tested on-wafer to ensure performance
compliance. The device is available in chip form.
Lead-Free and ROHS Compliant.
