Product Datasheet August 15, 2000 19 - 27 GHz Medium Power Amplifier TGA1073G-SCC Key Features and Performance • • • • • 0.25 um pHEMT Technology 22 dB Nominal Gain 25 dBm Nominal Pout @ P1dB Bias 5-7V @ 220 mA Chip Dimensions 2.55 mm x 1.15mm Primary Applications The TriQuint TGA1073G-SCC is a three stage MPA MMIC design using TriQuint’s proven 0.25 um Power pHEMT process. The TGA1073G is designed to support a variety of millimeter wave applications including point-to-point digital radio and point-to-multipoint communications. The TGA1073G provides 25dBm nominal output power at 1dB compression across 19-27GHz. Typical small signal gain is 22 dB. The TGA91073G 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. Point-to-Point Radio • Point-to-Multipoint Communications 25 20 Gain and Return Loss (dB) The three stage design consists of a 200 um input device driving a 480um interstage device followed by an 800um output device. • S21 15 10 5 0 -5 -10 S11 -15 -20 S22 -25 -30 18 19 20 21 22 23 24 25 Frequency (GHz) 19 20 21 22 26 27 28 28 24 P1dB (dBm) 20 16 12 8 4 0 23 24 25 26 27 28 29 Frequency (GHz) TriQuint Semiconductor Texas : Phone (972)994-8465 Fax (972)994 8504 Web: www.triquint.com 1 rev 11/10/98 Product Datasheet August 15, 2000 MAXIMUM RATINGS SYMBOL V+ VALUE PARAMETER 5/ NOTES POSITIVE SUPPLY VOLTAGE 8V POSSITIVE SUPPLY CURRENT 296 mA 1/ PIN INPUT CONTINUOUS WAVE POWER 23 dBm 4/ PD POWER DISSIPATION 2.37 W T CH OPERATING CHANNEL TEMPERATURE 150 0C I + TM T STG 2/ 3/ 0 MOUNTING TEMPERATURE (30 SECONDS) 320 C -65 to 150 0C STORAGE TEMPERATURE 1/ Total current for all stages. 2/ These ratings apply to each individual FET. 3/ Junction operating temperature will directly affect the device median time to failure (TM).
