| 21-23 GHz GaAs MMIC Medium Power Amplifier AA022P2-00 Features I Single Bias Supply Operation (6 V) I 22 dBm Typical P1 dB Output Power at 23 GHz I 14 dB Typical Small Signal Gain I 0.25 m Ti/Pd/Au Gates I 100% On-Wafer RF and DC Testing 0.000 3.400 RF IN 0.850 RF OUT Chip Outline 0.571 1.700 1.572 3.268 1.576 I 100% Visual Inspection to MIL-STD-883 MT 2010 0.000 Description Alpha's two-stage balanced K band GaAs MMIC power amplifier has a typical P1 dB of 22 dBm with 13 dB associated gain guaranteed across frequency range 21-23 GHz. The chip uses Alpha's proven 0.25 m MESFET technology, and is based upon MBE layers and electron beam lithography for the highest uniformity and repeatability. The FETs employ surface passivation to ensure a rugged reliable part with through-substrate via holes and gold-based backside metallization to facilitate a conductive epoxy die attach process. All chips are screened for small signal S-parameters and power characteristics prior to shipment for guaranteed performance. Dimensions indicated in mm. All DC (V) pads are 0.1 x 0.1 mm and RF In, Out pads are 0.07 mm wide. Chip thickness = 0.1 mm.
