CX74037  
Transmit RF IC for TDMA or AMPS Applications  
Conexant’s CX74037 Transmit RF Application-Specific Integrated Circuit (ASIC) is  
a triple-mode, dual-band transmitter intended for use in IS-136 compliant cellular  
phones. As a dual mode IC, it can be used in Time Division Multiple Access  
(TDMA) mode or Advanced Mobile Phone System (AMPS) mode. The device is  
available in a 48-pin 7x7 Land Grid Array (LGA) package with downset paddle.  
Features  
• Sectional enable lines for independent control of  
circuits within the chip  
• 90 dB IF VGA range  
• Separate IF frequencies can be used for the 800  
MHz (AMPS) and 1900 MHz Bands (PCS)  
• Dual drivers for 800 MHz and 1900 MHz  
• PA driver is deactivated by using the Driver Enable  
signal when there is no transmission  
• Available in a 48-pin, 7x7 LGA package with  
downset paddle  
The CX74037 RF IC device includes the following functional components:  
•
•
•
•
•
In-Phase and Quadrature (I/Q) modulator  
Two Intermediate Frequency (IF) Voltage Controlled Oscillator (VCO) inputs  
IF Variable Gain Amplifier (VGA)  
Two upconverters  
Two drivers for external Power Amplifiers (PAs).  
Applications  
The CX74037 48-pin, 7x7 LGA package pin configuration is shown in Figure 1. A  
CX74037 block diagram is shown in Figure 2.  
• Cellular and/or PCS-band phones  
• TDMA and/or AMPS-mode phones  
• Portable battery powered equipment
