Proposed 0 Typical Applications Pre-Driver for 450MHz Basestation Amplifiers PA Stage for Commercial Wireless Infrastructure RF3800 GaAs HBT PRE-DRIVER AMPLIFIER Class AB Operation for Cellular Radio and Wireless Local Loop Product Description The RF3800 is specifically designed for wireless infrastructure applications in 450MHz. Using a highly reliable GaAs HBT fabrication process, this high-performance single-stage amplifier achieves high output power over a broad frequency range. The RF3800 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 bias configurations are available to address a broad range of wireless infrastructure applications. -A- Pin 1 0.005 A 0.0025 0.200 REF 0.024 0.198 0.180 REF 0.236 0.156 0.025 R.008 0.050 TYP 0.028 TYP 0.050 REF 0.0780 MAX 0.020 7 PL Optimum Technology Matching® Applied Si BJT Si Bi-CMOS InGaP/HBT 9 Package Style: AlN GaAs HBT SiGe HBT GaN HEMT GaAs MESFET Si CMOS SiGe Bi-CMOS Features 6W Output Power High Linearity 45% Power-Added Efficiency Thermally-Enhanced Packaging Broadband Platform Design Approach VREF 1 NC 2 RF IN 3 NC 4 Bias Circuit 8 VBIAS 7 RF OUT 6 RF OUT 5 NC Ordering Information RF3800 GaAs HBT Pre-Driver Amplifier RF3800PCBA-416 Fully Assemb...
