Point-to-Point Radio
The TriQuint TGA188-EPU is a three stage
HPA MMIC design using TriQuint's proven
0.25 um Power pHEMT process to support a variety
of millimeter wave applications including
point-to-point digital radio, LMDS/LMCS and
Ka-band satellite spacecraft and ground terminals.
The three stage design consists of a 400 um input
device driving a pair of 600 um interstage devices
followed by four 600 um output devices. The device
is identical to TriQuint's TGA9070 with the exception
of additional bias circuitry that allows the flexibility to
operate in two different modes. The high saturated
power mode will give identical performance to the
TGA9070. The high linearity mode will provide 2-3dB
improvement in OTOI performance over the TGA9070.
The TGA1088 provides greater than 1W of
output power across 23-29 GHz with a typical
PAE of 35%. Typical small signal gain is 23 dB.
The device may be biased for either high saturated
power or high linearity via bond wire jumpers.
The TGA188 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.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
