RF2890

The RF2890 is a high performance dual band CDMA Cellular and GPS LNA/mixer. An integrated optional LO prescaler allows VCO flexibility. The device is designed to exceed all sensitivity, intermodulation and single-tone requirements. The RF2890 is designed for three state gain control solutions (17.5dB of gain control) for cellular band IMD testing. The device offers a dedicated low current (15.5mA) GPS LNA/mixer with 32.5dB gain. An integrated TX L O buffer is also included. The design is flexible, in that the bias currents may be set using off-chip current reference resistors for the mixer and LNA blocks. Noise figure, IIP3, and other specifications are designed to be compatible with the TIA/EIA 98D standard for CDMA  cellular communications. The device is packaged in a plastic, 4mmx4mm QFN.
