RF Micro Devices introduces the RF3404, a fully integrated dual band front-end module for tri-mode CDMA applications. This SiGe HBT based 8 3 8 mm receive module reduces board area by 70% and decreases bill of materials component count by 22 components. The module features two complete RF downconverters with low noise amplifiers, RF SAW filters, TX LO buffers, and internal RF matching for PCS and cellular band frequencies. The module is designed with an optional LO frequency divider which provides the flexibility to use either single or dual VCO architectures. Multiple gain control options are available to conserve current consumption and meet IS-98B specifications. All of the required RF matching, bias circuitry and decoupling capacitors are included in the module, which is control-compatible with existing IF-to-baseband solutions.
