Product Description
The RF3809 is a GaAs pre-driver power amplifier, specifically designed for wireless infrastructure applications. Using a highly reliable GaAs HBT fabrication process, this high-performance single-stage amplifier achieves high output power over a broad frequency range. The RF3809 also provides excellent efficiency and thermal stability through the use of a thermally-enhanced surfacemount plastic-slug package. Ease of integration is accomplished through the incorporation of an optimized evaluation board design provided to achieve proper 50Ω operation. Various evaluation boards are available to address a broad range of wireless infrastructure applications: NMT 450MHz; GSM850MHz; GSM900MHz; DCS1800MHz; PCS1900MHz; and, UMTS2200MHz.
