Product Datasheet 23 - 29 GHz High Power Amplifier TGA9070-SCC Key Features and Performance • • • • • • 0.25um pHEMT Technology 23 GHz - 29 GHz Frequency Range Nominal 1 Watt (28GHz) @ P1dB Nominal Gain of 23 dB Bias 7V @ 400 mA Chip Dimensions 4.1mm x 3.0mm Primary Applications • LMDS • Point-to-Point Radio Description The TriQuint TGA9070-SCC 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 TGA9070 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 TGA9070 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.
