RF2451 General Description
The RF2451 is a general purpose, low-cost, high performance low noise amplifier designed for operation from a 2.7V to 4V supply with low current consumption. The attenuation of the device is controlled when in power down mode, providing a known gain step. The RF2451 is available in a small industry-standard MSOP-8 surface mount package, enabling compact designs which conserve board space. The design features accurate PTAT (Proportional To Absolute Temperature) biasing scheme using band gap cells.

RF2456 General Description
The RF2456 is a receiver dual downconverter designed for the receive section of dual-mode CDMA/FM cellular applications. It is designed to downconvert RF signals while providing 13dB gain in CDMA mode, and 7dB gain in FM mode. It also features digital control of IF output selection and power down mode. Noise Figure, IP3, and other specs are designed to be compatible with the IS-95 Interim Standard for CDMA cellular communications. The IC is manufactured on an advanced Silicon Bipolar process and packaged in an SSOP-16.
