RF2870 - CDMA LOW NOISE AMPLIFIER/MIXER 900MHz DOWNCONVERTER

Description

-A- CDMA LOW NOISE AMPLIFIER/MIXER 900MHz DOWNCONVERTER General Purpose Downconverter Commercial and Consumer Systems

The RF2870 is a receiver front-end for CDMA cellular applications.

Features

  • include digital control of LNA gain, mixer gain, and power down mode. Another feature of the chip is adjustable IIP3 of the mixer using an off-chip current setting resistor. Noise figure, IP3, and other specs are designed to be compatible with the IS-98B interim standard for CDMA cellular communications. The IC is manufactured on an advanced Silicon Germanium BiCMOS process and is assembled in a 3mmx3mm, 16pin, QFN package. 1.50 TYP 2 PLCS 0.90 0.85 0.70 0.65 0.10 C B 0.05 0.00 3.00 12° MAX.
