• CDMA/AMPS Cellular Systems
•PCSSystems
• Portable Battery-Powered Equipment
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.
• Single Supply 3.0V Operation
• Power Down Control
• Gain Control Range of 22dB
• Driver Amplifier Select Pin (RF Output
Select)
• High Linearity in Mixer and Driver Amp
