General Description

The 0.25-m mmW pHEMT 2MI (2-metal-interconnect)
process utilizes T-gate depletion-mode transistors and is
optimized for high-power and low-noise applications
through 50 GHz. Passives include 2 thick-metal intercon-
nect layers, precision TaN resistors, GaAs resistors, MIM
capacitors and through-substrate vias. The via-under-cap
process aids in size compaction and offers excellent
grounds at higher frequencies. Air bridges produce minimal
interconnect capacitance. This process is suitable for com-
mercial, military and space applications.

Application Examples
17 to 27 GHz High Power Amplifier TGA4502-EPU:
This high-power amplifier is used primarily for K-band satellite communications and point-to-point
radio. It has 29 dBm nominal output power at 1-dB gain compression and 37 dBm nominal output
TOI.

28 to 31 GHz Ka Band High-Power Amplifier TGA4501-EPU:
This power amp has 34.5 dBm nominal output power at 1-dB gain compression and 40 dBm typi-
cal output TOI. It is used in satellite ground terminals and point-to-point radios.

36 to 40 GHz 1 Watt Power Amplifier TGA1171-SCC:
The Ka-band high-power amplifier is a two-stage power amplifier for point-to-point digital radio
and point-to-multipoint systems.

26 to 35 GHz Medium Power Amplifier TGA1073A-SCC:
This medium-power amplifier provides 25 dBm nominal output power at 1-dB gain compression
across 26 to 35 GHz. Typical small-signal gain is 19 dB. The TGA1073A is designed to support a
variety of millimeter wave applications including point-to-point digital radio and LMDS/LMCS.
