| CX74036 IS-136 Receive RF IC for TDMA and AMPS Applications 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. The CX74036 48-pin, 7x7 Land Grid Array (LGA) package pin configuration is shown in Figure 1. A block diagram of the CX74036 is shown in Figure 2.

CX74036 Functional Block Diagram Technical Description 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.

RF Mixer Load Configuration 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. 101105A October 17, 2000 2 Conexant - Proprietary Data Subject to Change Receive RF IC CX74036 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. Control Logic Truth Table.
