RF3404 Preliminary 8 DUAL-BAND/TRI-MODE CDMA LOW NOISE AMPLIFIER/MIXER MODULE Typical Applications • CDMA Cellular/PCS Handsets Product Description 0.5 CDMAIF+ The RF3404 is a fully-functional, integrated dual-band downconverter module for tri-mode CDMA applications. The module, which uses SiGe technology, features two complete RF downconverters with low noise amplifiers, RF SAW filters, TX LO buffers, and RF matching for PCS and cellular band frequencies. Additionally, a divide-by-2 prescaler is integrated to allow the use of a single-band VCO. Multiple gain control options are available to conserve current and meet IS-98B specifications. The mixer design allows for a common IF filter for CDMA cellular and PCS operation, and a second output for the FM output. IF matching is external to the module. 0.6 22 VCC1 21 CDMAIF- 23 15 BAND SEL VCC4 44 43 FM IF+ IF SEL FM IF- IP SET 39 38 PCS LNA IN Si BJT GaAs HBT üSiGe HBT Si Bi-CMOS DIV ENABLE CELL LNA IN 11 LO IN VCC3 48 28 PCS LO OUT 35 ENABLE TX BUFFER ENABLE 29 30 CELL LO OUT LNA GAIN 34 MIXER GAIN 1 8 9 VCC2 8 0.1 FRONT-ENDS 8.00 sq.

The RF3404 is control-compatible with existing IF-to-baseband solutions. Electrical Design Overview The heart of the module is the RF2489 SiGe monolithic microwave integrated circuit (MMIC) based on a highperformance silicon germanium (SiGe) process. The SiGe process is capable of fabricating transistors with an Ft of 47GHz. The module achieves 30dB of gain control in the 880MHz band. The gain-control range is obtained with switches around the LNA and mixer preamplifier. By itself, the cellular LNA features 15dB small-signal gain and a typical noise figure of 1.1dB when drawing 6mA current from a +2.75VDC supply. A CMOS-enabled control line makes it possible to select an increased LNA input third-order intercept point of +10dBm to meet the cross modulation requirements of the IS-95B CDMA specification. The RF3404's LNA is followed by a miniature RF SAW filter. It provides RF image rejection as well as transmit-band rejection. All impedance matching to the RF SAW filter is contained within the module. The module's RF2489 SiGe MMIC contains two high-frequency mixers that handle downconversion of the CDMA and AMPS signals at 880MHz. The module provides a common IF port for the CDMA cellular and PCS band output signal and a separate IF output port for the AMPS-band IF signal. The mixers and their integrated preamplifiers achieve a noise figure of 7dB, gain of 14dB, and input third-order intercept point of +3dBm. A bypass switch around the mixer preamplifier is integrated to support those systems using a two-step gain approach for meeting the three test conditions of IS-95B intermodulation performance Rev A1 010918 The 1960MHz PCS CDMA signal path is similar to the cellular path in many ways. The PCS LNA has a typical gain of 16dB with a noise figure of 1.3dB. The LNA can also be bypassed and also has a setting for high input third-order intercept point of +8dBm. The PCS mixer features 13dB gain, 7dB noise figure, and input thirdorder intercept point of +3dBm. Again, all of the RF impedance matching to the LNA and SAW filters is included in the module. The RF3404 module is flexible enough to accommodate either single or dual voltage-controlled-oscillator (VCO) architectures. The cellular band has the selectable option of running the LO directly to the cellular mixers or routed through a divide-by-2 frequency prescaler for systems that have migrated to a single VCO architecture. A buffered transmit LO output with -12dBm output power is also supplied for both the PCS and cellular bands. The RF3404 requires an input LO power range of -10dBm to -4dBm. The LO input port is matched to 50Ω. The LO outputs can be tied together externally to support single transmit LO applications and each is matched to 50Ω. Mechanical Layout Overview The RF3404 is built around a laminate module technology geared to high-volume manufacturing and the low cost structure mandated by the wireless industry. RF Micro Devices has already built millions of power amplifier (PA) modules using the same materials sets, supply chain, and manufacturing rules used for the RF3404. The module is overmolded with a compound that has a finished overall thickness of 1.6mm. The backside pattern of the 8.0mm x8.0mm module is a 48-pin land grid array (LGA) with a double row of input/output (I/O) connections to ease trace routing as shown in the interface outline drawing. A total of 21 of these I/O pads are actual signal interconnections, with the remainder being ground connections. The I/O pads are a generous 0.5mmx0.6mm in size on a 1.0mm pitch. The outer ring of I/O pads contains all of the RF connections along with the voltage supply and some control lines. The inner ring of I/Os contains only DC control signal lines and VCC connections. A 1.5mm square ground pad in the center of the module backplane supplies additional RF grounding and also assures a very robust mechanical attachment to the cellular/PCS telephone PCB. The dual row I/Os aid in the telephone PCB layout by reducing the number of 8-41 8 FRONT-ENDS Why Design with Receive Modules? The RF3404 is a fully integrated dual-band, tri-mode module contains an LNA, RF image-rejection SAW filter, mixer, mixer preamplifier, and local oscillator (LO) buffer amplifiers as shown in the block diagram. The module also contains all of the RF matching components, bias-setting components, and decoupling components required. The differential IF output matching is external to the module in part due to the varying range of IFs used by customers and the physical size of IF SAW filters. The module, which measures only RF3404 Preliminary Simplify the Supply Chain The supply chain can be significantly simplified with the elimination of two dozen components that would not need to be source selected, qualified, purchased, received, stored, coordinated or delivered to the factory floor. traces required to converge on the perimeter of the module. Routing is eased by viaholes that can be placed between the inner row of connections and the center ground pad in the cellular/PCS telephone PCB. FRONT-ENDS 8 Why Use Integrated Modules? Decreased Board Area Table A shows a comparison between the leading four design approaches for dual-band/tri-mode CDMA front ends: 1. discrete LNAs and discrete mixers with off-chip matching for each component, 2. single band cellular and PCS LNA/Mixer MMICs with off-chip matching, 3. single MMIC dual band chips with off-chip matching and finally 4. fully integrated modules like the RF3404. Table A summarizes the number of SMD components for each approach as well as the typical amount of phone board space required for a complete layout.The RF3404 represents a 50 percent to 70 percent reduction in the amount of board space required when compared with the most highly integrated chip solutions on the market today. Furthermore, it represents the largest percentage improvement in board space savings for any of the other increased integration gains in recent years. Decreased Engineering and Product Cycle Time With a single module solution the RF engineering required to design the front end is significantly reduced. The RF3404 module allows for a design-in solution meeting all of the IS95B requirements, which requires significantly less engineering. Decreased Assembly Costs Accordingly, assembly costs are also reduced. With SMD placement costs running in the range of 1.0cents to 1.3cents per placement and with the placement of die packages, SAWs, and modules costing even more per placement, one can eliminate somewhere around 35cents from the cost of assembly with modules and improve factory throughput. Improve Phone Level Yield Known good RF performance at the module level is available with integrated modules that have been RF tested. Phone level yield can be improved, in addition to the improvement in yield from placing two dozen fewer components. Reduced BOM Counts Another area where one can see marked improvement is in BOM reduction. The RF3404 reduces the BOM from the most highly integrated alternatives available today that contain approximately 25 components to only three. The three are VCC-bypassing capacitors that depend on the frequency response of the phone board power supply and a resistor. Improved Reliability Mechanical attachment and reliability is improved with this module technology due to a variety of factors. The first is the elimination of numerous components and thus solder joints, which directly aids overall phone reliability. Another important factor is the matched coefficient of thermal expansion (CTE) between the laminate module and the cellular/PCS telephone PCB that eliminates much of the solder stress potential found in lowtemperature-cofired-ceramic (LTCC) or chip-scale modules and should provide the most robust solution for the stringent mechanical shock and drop tests that mobile telephone hardware must survive.
