CONEXANT CX74036

CX74036
IS-136 Receive RF IC for TDMA and AMPS Applications
Features
Conexant’s CX74036 receive RF IC is an advanced, highly integrated and high
performance, triple-mode, dual-band IC for IS-136 compliant cellular radio
applications and is designed in an advanced 28 GHz Ft BiCMOS process. In the
800 MHz cellular band, the CX74036 is designed to operate in both the Time
Division Multiple Access (TDMA) mode and Advanced Mobile Phone System
(AMPS) mode. In the 1900 MHz Personal Communications System (PCS) band,
the device operates in the TDMA mode.

The CX74036 embodies all the necessary functions for a radio receiver system
except for the RF and Intermediate Frequency (IF) filters and RF Local Oscillator
(LO) sources. The device front-end section has two Low Noise Amplifier (LNA) and
mixer pairs, one for the 800 MHz band and the other for the 1900 MHz band. A
common path is taken from the first IF mixer output to the demodulator output.

Technical Description
Vcc
Low Noise Amplifiers: The CX74036 contains two
independent LNAs for the cellular and PCS bands. The gain of
both LNAs can be switched off to a loss mode via one command
line interface. Only one LNA is powered at any given time.
Control is done by an external band-select control signal. The
input and output matches are external to the chip. The LNAs’
parameters, Noise Figure (NF), and gain are chosen to provide
an excellent balance between system sensitivity and IIP3
requirements to achieve maximum dynamic range. Both LNA
outputs are ported off-chip to allow for image filtering before
being fed to the RF mixer inputs.
RF Mixers: The mixers are designed to operate with a low LO
input power level of –10 dBm. This eliminates the requirement of
buffer amplifiers for the external VCO. Cellular band mixer high
gain and low NF performance allow for the cellular LNA gain to
be lower, which saves current consumption. Both mixers are
designed to provide high suppression of one-half IF response.
The outputs of both mixers share a common interface path to
the external IF Surface Acoustic Wave (SAW) filter, which
reduces complexity and cost. The RF mixer load configuration is
shown in Figure 3. Inductors can be Surface Mount Multilayer
Chip (SMMC) components.
First IF Mixer: This mixer begins the common signal path for
both cellular and PCS band modes. Input and output impedance
are set to values that are close to the most commonly available
SAW and ceramic filters.

Variable Gain Amplifier: The VGA itself provides 70 dB of
dynamic range to satisfy the high system dynamic range
requirement. With the inclusion of the LNA gain switch, the
system dynamic range is extended to more than 95 dB.
I/Q Demodulator: Using digital circuitry generates a stable
quadrature LO signal, on-chip direct connection to the VGA
output, on-chip LO source, and lowpass filtering for each
channel. This, in turn, provides a high performance I/Q
demodulator with very low amplitude and phase offsets. The
output signal quality is compatible with many baseband interface
requirements.

Electrical and Mechanical Specifications ________________
VHF Synthesizer and Oscillator: The on-chip VHF synthesizer
and an oscillator with an added external tank circuit generate
the required second IF LO signal for conversion down to the
standard second IF signal. A programmable divide circuit is also
included to generate the LO for the I/Q demodulator. Depending
on the frequency plan used, an option is provided to inject an
external LO source for the I/Q demodulator.
The signal pin assignments, names, and descriptions are found
in Table 3. Absolute maximum ratings are provided in Table 4,
the recommended operating conditions are specified in Table 5.
Electrical characteristics are shown in Table 6.
