RF2498 General Description
The RF2498 is a high performance CDMA tri-band/quadmode integrated LNA/mixer with GPS capability. The device is designed to meet all IS-98 sensitivity, intermodulation and single-tone requirements. The RF2498 integrates the tri-band LNA/downconverters with 27.5dB of gain control for the cellular band and 29dB for the PCS band. The RF2498 is designed for three state gain control solutions for IS-98 IMD testing. The device offers a dedicated GPS LNA/mixer with 37dB of gain. Additionally, a divide-by-2 prescaler to allow the use of either a single- or dual-band VCO is integrated. There is also a TX LO buffer. The design is flexible, in that the bias currents may be set using off-chip current reference resistors for the mixer and LNA blocks. The device is packaged in a plastic, 5mmx5mm, leadless chip carrier.
