IFT3000
The circuit blocks within the IFT3000 device
include digital-to-analog converters (DACs) for
converting digital baseband to analog baseband,
lowpass filters, a mixer for upconverting to IF and
an 85 dB dynamic range Tx AGC amplifier. The
IFT3000 device includes a fully programmable
phase-locked loop (PLL) for generating Tx LO and IF frequencies. The
IFT3000 device also has an 8-bit general-purpose ADC with three
selectable inputs for monitoring battery level, RF signal strength and
phone temperature.
IFT3000 Device Features
Supports IS-98 (CDMA) and IS-19 (AMPS) standards for dual-mode
operation
Operates on 2.7 to 3.15 V supply voltage
8-bit DACs convert digital baseband signals to analog baseband
CDMA and FM signal paths include lowpass filters for I and Q
output waveform smoothing
IF mixer upconverts analog baseband to IF
Tx power control through 85 dB dynamic range AGC amplifier
Programmable Tx PLL for generating Tx IF frequency
VCO for generation of Tx LO mixing signal
8-bit general-purpose ADC with 3-input analog multiplexer and
selectable input ranges
