Product Description
The RF2643 is a complete upconverter, dual-power amplifier driver and attenuator designed for Cellular and PCS systems. It is designed to upconverter and amplifies RF signals while providing 22dB of linear gain control range. It features digital control for the mixer and drivers. The device features balanced IF inputs, single-ended LO input and dual RF output for Cellular and PCS Systems respectively. The IC is manufactured on an advanced Silicon Bi-CMOS process and packaged in a 20-pin, 4mmx4mm, leadless chip carrier with an exposed die flag.
