Ka band 1 watt amplifier chip
ka1W
Frequency Range: 31.5 – 37GHz
Parameter @ 35 GHz
30.8 dBm Nominal Psat
30.0 dBm P1dB
21 dB Nominal Power Gain
Bias: Vd=5.5,6 V @ Vg=-0.7V
0.15 um pHEMT Technology
Chip Dimensions: 3.975 x 1.992 x 0.10 mm
The Ka1W die is produced using standard 0.15um power pHEMT process.
It can replace TGA1141 .
The Ka1W nominally provides 30.8 dBm saturated output power, 33dBm output
power at 1dB Gain compression @ 35 Ghz and has typical gain of 21 dB.
The part is ideally suited for low cost emerging markets such as Communications
Satellites, and Image and SAR Radar.
The Ka1W chip is 100% DC and RF tested on wafer to ensure performance
compliance.
