Description

The RF2658 is an integrated complete Quadrature Modulator, IF AGC amplifier, and Upconverter developed for the transmit section of dual-mode CDMA/FM cellular and PCS applications and for GSM/DCS and TDMA systems. RF2658 is designed to modulate baseband I and Q signals, amplify the resulting IF signals while providing 95dB of gain control range, and perform the final upconversion to UHF. Noise Figure, IP3, and other specifications are designed to be compatible with the IS-98 Interim Standard for CDMA cellular communications. This circuit RF2658 is part of RFMD's line of complete solutions for digital radio applications. The IC is manufactured on an advanced 15GHz FT Silicon Bipolar process, and is supplied in a 28-lead plastic SSOP package.
