QPA7489A DC3500MHz Cascadable SiGe HBT Amplifier Product Overview The QPA7489A is a high performance SiGe HBT MMIC amplifier. A Darlington configuration provides high FT and 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 3 Lead SOT-89 Package intermodulation products. The QPA7489A may be operated from a variety of supply Key Features voltages by using a voltage dropping resistor. Two DC- DC to 3500 MHz Operation blocking capacitors, bypass capacitors and an optional RF choke complete the circuit required for operation of this Single Positive Voltage Supply internally matched 50 ohm device. Cascadable 50 Gain: 17.7dB at 1950MHz The QPA7489A is assembled in an industry standard SOT- Output IP3: +37.7dBm typical at 850MHz 89 package that is lead-free and RoHS-compliant. Noise Figure: 3.2dB Typical at 1950MHz Low Thermal Resistance SOT-89 Package Functional Block Diagram Lead-free/RoHS-Compliant Applications Cellular, PCS, GSM, UMTS Power Amplifier Driver IF/RF Buffer Amplifier Wireless Data, Satellite Top View Ordering Information Part No. Description QPA7489ASQ 25 Piece Sample Bag QPA7489ASR 100 Pieces on 7 Reel QPA7489ATR13 3000 pieces on a 13 reel QPA7489APCK401 850MHz, EVB with 5 Piece Sample Bag Data Sheet, May 14, 2021 Subject to change without notice 1 of 7 www.qorvo.com QPA7489A DC 3500MHz Cascadable SiGe HBT Amplifier Absolute Maximum Ratings Recommended Operating Conditions Parameter Rating Parameter Min Typ Max Units Storage Temp 55 to +150C Operating Temperature 40 +85 C Device Voltage (VD) +7 V Junction Temperature (TJ) +125 C Electrical specifications are measured at specified test conditions.
