RF2643 Datasheet | RF Micro Devices

Description The RF2643 is a plete upconverter, dual-power amplifier driver and attenuator designed for Cellular and PCS systems. It is designed to upconverter and amplifies RF signals while providing 22d B 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. 1.00 0.90 0.60 0.24 typ 4.00 sq. 0.65 0.30 4 PLCS 3 0.20 2.10 sq.
