The RF2498 is a high performance CDMA tri-band/quad-

mode integrated LNA/mixer with GPS capability. The

device is designed to meet all IS-98 sensitivity, intermod-

ulation and single-tone requirements. The RF2498 inte-

grates 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 dedi-

cated 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 plas-

tic, 5mmx5mm, leadless chip carrier.

• GPS Receive Front-End Gain=37dB

• Meets IMD Tests with Three Gain

States/Two Logic Control Lines

• Adjustable Mixer and LNA Bias Current

• Selectable Divide-by-2 Prescaler
