QPA4486A DC4500MHz Cascadable SiGe HBT Amplifier General Description The QPA4486A is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration provides high F and T excellent thermal performance. The heterojunction increases breakdown voltage and minimizes leakage current between junctions. Cancellation of emitter junction non-linearities results in higher suppression of intermodulation products. Only two DC-blocking capacitors, a bias resistor, and an optional RF choke are required for 4 Lead SOT-86 Package operation. Product Features DC to 4500 MHz Operation High Gain: 16.5dB at 1950MHz Cascadable 50 Operates from Single Supply Low Thermal Resistance Package Applications Instrumentation Functional Block Diagram Repeaters Boosters PA Driver Amplifier Cellular, PCS, GSM, UMTS 4 IF Amplifier Wireless Data, Satellite 1 3 2 Ordering Information Part No. Description Top View QPA4486ATR13 3000 pieces on a 13 reel (standard) QPA4486ASQ 25 Piece Sample Bag QPA4486ASR 100 Pieces on 7 Reel QPA4486APCK401 850MHz, +8V EVB with 5 Piece Sample Bag Data Sheet March 27, 2017 Subject to change without notice 1 of 7 www.qorvo.com QPA4486A DC4500MHz Cascadable SiGe HBT Amplifier Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Storage Temp 55 to +150C Operating Temperature 55 +105 C Device Voltage (V ) +5 V Junction Temperature (T ) +125 C D J Device Current (ID) 90 mA Device Operating Voltage +2.9 +3.2 +3.5 V Electrical specifications are measured at specified test conditions.
