RF2461 - CDMA/FM LOW NOISE AMPLIFIER/MIXER 900MHZ DOWNCONVERTER

Datasheet Summary

Description

The RF2461 is a receiver front-end designed for the receive section of dual-mode CDMA/FM cellular applications.

It is designed to amplify and downconvert RF signals, while providing 30dB of stepped gain control range.

Features

  • include digital control of LNA gain, mixer gain, and power down mode. Another feature of the chip is adjustable IIP3 of the LNA and 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 HBT process and is in a 4mmx4mm, 20-pin, leadless chip carrier. 1.00 0.90 0.60 0.24 typ 4.00 sq. 4 PLCS 0.65 0.30 3 0.20 2.
