The RF2658 is an integrated complete Quadrature Modu-
lator, 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.
It 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, IP
3
, and other specifications are
designed to be compatible with the IS-98 Interim Stan-
dard for CDMA cellular communications. This circuit is
part of RFMD’s line of complete solutions for digital radio
applications. The IC is manufactured on an advanced
15GHz F
T
Silicon Bipolar process, and is supplied in a
28-lead plastic SSOP package.
