1 Applications Short Haul / High Capacity Links Sensors X=23 mm Y=16 mm Product Features RF Frequency: 92 to 96 GHz Linear Gain: 7.5 db typ. Psat: 25 dbm typ. Die Size: 3.7 sq. mm. 2 mil substrate DC Power: 4 48 ma Product Description The APH482 monolithic HEMT amplifier is a broadband, two-stage power device, designed for use in commercial digital radios and wireless LANs. To ensure rugged and reliable operation, HEMT devices are fully passivated. Both bond pad and backside metallization are Ti/Au, which is compatible with conventional die attach, thermocompression, and thermosonic wire bonding assembly techniques.
