| Proposed 0 Typical Applications RF3805 GaAs HBT PRE-DRIVER AMPLIFIER * GaAs HBT Pre-Driver for Basestation Amplifiers * Class AB Operation for GSM/EDGE/ * Power Amplifier Stage for Commercial Wireless Infrastructure CDMA2000/W-CDMA Transmitter Applications Product Description The RF3805 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 RF3805 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 operation. Various evaluation board configurations are available to address a broad range of wireless infrastructure applications: * GSM/EDGE1800 * CDMA2000 * W-CDMA Optimum Technology Matching(R) Applied Si BJT Si Bi-CMOS InGaP/HBT GaAs HBT SiGe HBT GaN HEMT GaAs MESFET Si CMOS SiGe Bi-CMOS -A- Pin 1 0.005 A 0.0025 0.200 REF Shaded circle designates pin 1 location. 0.024 0.198 0.180 REF 0.236 Dimensions in inches. 0.156 0.025 R.008 0.050 TYP 0.028 TYP 0.050 REF 0.0780 MAX 0.020 7 PL Package Style: AlN Features * 5W Output Power * High Linearity * 40% Power-Added Efficiency * Thermally-Enhanced AlN Packaging * Broadband Platform Design Approach VCC1 1 VREF 2 RF IN 3 V_BIAS 4 Bias Circuit 8 RF OUT/VCC2 7 RF OUT/VCC2 6 RF OUT/VCC2 5 RF OUT/VCC2 Ordering Information RF3805 RF3805PCBA-411 RF3805PCBA-412 RF3805PCBA-413 RF3805PCBA-414 RF3805PCBA-415 GaAs HBT Pre-Driver Amplifier Fully Assembled Evaluation Board - 1625 to 1665 Fully Assembled Evaluation Board - 1710 to 1785 Fully Assembled Evaluation Board - DCS1800 Fully Assembled Evaluation Board - PCS1900 Fully Assembled Evaluation Board - UMTS2100 Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com PACKAGE BASE GND Functional Block Diagram RF Micro Devices, Inc. 7628 Thorndike Road Greensboro, NC 27409, USA Rev A1 040806 4-631 RF3805 Proposed Please contact RF Micro Devices Applications Engineering at (336) 678-5570 for more information. 4-632 Rev A1 040806 |
