1 -; Rev ; / EVAUATION KIT MANUA FOOWS DATA SHEET Adjustable, High-inearity, General Description The MAX/MAX/MAX/MAX/MAX/ MAX high-performance silicon germanium (SiGe) receiver front-end ICs set a new industry standard for low noise and high linearity at a low supply current. This family integrates a variety of unique features such as an O frequency doubler and divider, dual low-noise amplifier (NA) gain settings, and a low-current paging mode that extends the handset standby time. The MAX family includes six ICs: four operate at both cellular and PCS frequencies, one operates at cellular frequencies, and one at PCS frequencies (see Selector Guide). Each part includes an NA with a high input third-order intercept point (IIP) to minimize intermodulation and cross-modulation in the presence of large interfering signals. In low-gain mode, the NA is bypassed to provide higher cascaded IIP at a lower current. For paging, a low-current, high-gain mode is provided. The CDMA mixers in cellular and PCS bands have high linearity, low noise, and differential IF outputs. The FM mixer is designed for lower current and a single-ended output. All devices come in a -pin TSSOP-EP package with exposed paddle (EP) and are specified for the extended temperature range (- C to + C).

15 Detailed Description ow-noise Amplifier Within its operating bands, each device in the MAX family (except the MAX) has three modes of NA operation: high gain, high linearity (HGH); high gain, low linearity (HG); and low gain, high linearity (GH). The logic inputs control the NA mode as described in the AC Electrical Characteristics. Use HGH mode when extra-high NA linearity is required for cross-modulation suppression. Use HG mode when the transmitter is off and cross-modulation is not a concern. When the NA changes modes, the input VSWR change is minimal. Use GH mode for receiving large signals and when high sensitivity is not required. The MAX NA has only an HG mode. Adjust the HGH mode NA linearity by changing R RNA, and adjust linearity of the other modes by changing R RBIAS. Downconverter The downconverters in these devices are double-balanced mixers. The PCS-band mixer and digital cellularband mixer share the same IF output ports. The cellular band FM mixer has its own IF output to feed a different filter. Adjust the downconverter linearity and current by changing RRBIAS (see Typical Operating Characteristics). When the linearity requirement is high, the mode control inputs increase the current in the downconverter. When the linearity requirement is not high, the current is lower. O Output Buffers The BUFFEN logic input turns the open-collector O output buffers on and off. This feature saves current if the buffers are not required. Operational Modes Each device has logic input pins that control the different operational modes listed in Tables. MAX/MAX/MAX Operation The MAX/MAX/MAX are dual-band, triplemode receivers that amplify and downconvert cellularand PCS-band signals. They consist of cellular and PCS NAs; cellular digital, cellular FM, and PCS digital mixers; and cellular and PCS O buffers. The MAX has an O frequency doubler on-chip, so a single cellularband VCO can be used for both the cellular- and PCSband mixers. Selecting the PCS path activates the O frequency doubler. The MAX has an O divide-bytwo circuit, so a single PCS-band VCO can be used for both the cellular and PCS mixers. Selecting the cellular path activates the O divide-by-two circuit. Three logic input pins BAND, GAIN, and IN control eight operational modes of the NAs and mixers. The modes are summarized in Table. MAX///// Table. MAX/MAX/MAX Operational Modes DESCRIPTION Shutdown.

16 MAX///// MAX Operation The MAX is a lower-cost PCS-only version that can be installed as a drop-in replacement for the dual-band versions. It consists of a PCS NA, PCS mixer, pinselectable O frequency doubler, and O buffer. ogic input SHDN = / GND turns on/off the entire IC except the O buffer. The OX logic input controls the O frequency doubler. OX = GND disables the doubler when using a PCS band VCO, and OX = VCC activates the doubler when using a cellular-band VCO. GAIN and IN logic inputs control the MAX s three operational modes, as summarized in Table. MAX Operation The MAX is a lower-cost cellular-only version that can be installed as a drop-in replacement for the dualband versions. It consists of a cellular NA, cellular digital mixer, cellular FM mixer, and O buffer. A SHDN logic input turns on/off the entire IC except the O buffer. GAIN and IN logic inputs control the MAX s three operational modes, as summarized in Table. MAX Operation The MAX is similar to the MAX except it only features an HG mode, and either O output buffer is selectable during shutdown. It consists of PCS and cellular NAs; PCS, cellular digital, and cellular FM mixers; and PCS and cellular O buffers. A SHDN logic input turns on/off the entire IC except the O buffer. BAND and MODE logic inputs control the MAX s three operational modes, as summarized in Table. Applications Information Cascaded NA/Mixer Performance The NA and mixer design aims at optimizing cascaded performance in all gain and linearity modes. In highgain, high-linearity mode, both the NA and mixer have a low noise figure, high gain, and high linearity. The NA has high gain to minimize the noise contribution of the mixer, thus increasing the receiver s sensitivity and extra-high linearity for superior cross-modulation suppression. The HG mode is used when the transmitter is off and cross-modulation is not a concern. In lowgain, high-linearity mode, the received signal is strong enough that linearity is the primary concern. The NA gain is reduced for higher system linearity. Tables and summarize the cascaded performance. S Parameters The S parameters are listed in Tables.

17 ayout Considerations Keep RF signal lines as short as possible to minimize losses and radiation. Use high-q components for the NA input matching circuit to achieve the lowest possible noise figure. At the digital mixer outputs, keep the differential signal lines together and of equal length to ensure signal balance. For best gain and noise performance, solder the slug evenly to the board ground plane. Table.
