RF3802

RF3802 0 RoHS Compliant & Pb-Free Product Typical Applications • GaAs HBT Pre-Driver for Basestation Amplifiers • Class AB Operation for GSM/EDGE/CDMA • Power Amplifier Stage for Commercial Wireless Infrastructure Transmitter Applications GaAs HBT PRE-DRIVER AMPLIFIER Product Description The RF3802 is specifically designed for wireless infrastructure applications. Using a highly reliable GaAs HBT fabrication process, this high-performance dual-stage amplifier achieves high output power over a broad frequency range. The RF3802 amplifier also provides excellent efficiency and thermal stability through the use of a thermally-enhanced surface-mount AlN package. Ease of integration is accomplished through the incorporation of an optimized evaluation board design provided to achieve proper 50 Ω operation. Various evaluation board configurations are available to address a broad range of wireless infrastructure applications: • AMPS/GSM850/EDGE850 • GSM900/EDGE900 • IS-95/CDMA2000/AMPS Optimum Technology Matching® Applied Si BJT Si Bi-CMOS InGaP/HBT GaAs HBT SiGe HBT GaN HEMT GaAs MESFET Si CMOS SiGe Bi-CMOS Pin 1 0.005 A -A0.0025 0.200 REF 0.024 0.200 0.180 REF 0.238 Dimensions in inches. 0.050 REF 0.078 REF 0.156 0.025 R.008 0.050 TYP 0.025 TYP 0.175 0.005 TYP 0.022 7 PL SCALE - 16:1 0.003 TYP Package Style: AlN Features • 5W Output Power • High Linearity • 35% Power-Added Efficiency • Thermally Enhanced AlN Packaging • Broadband Platform Design Approach VCC1 1 VREF 2 RF IN 3 VBIAS 4 Bias Circuit PACKAGE BASE GND 8 RF OUT/VCC2 7 RF OUT/VCC2 6 RF OUT/VCC2 5 RF OUT/VCC2 Ordering Information RF3802 GaAs HBT Pre-Driver Amplifier RF3802PCBA-410 Fully Assembled Evaluation Board - GSM850 RF3802PCBA-411 Fully Assembled Evaluation Board - GSM900 Functional Block Diagram RF Micro Devices, Inc. 7628 Thorndike Road Greensboro, NC 27409, USA Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com Rev A6 050609 4-631 RF3802 Absolute Maximum Ratings Parameter Supply Voltage (VCC) Power Control Voltage (VREF) DC Supply Current Input RF Power Output Load VSWR Operating Ambient Temperature Storage Temperature Rating 9 9 2000 23 5:1 +85 +125 Unit VPC V mA dBm °C °C Caution!
