Quadruple-Mode PCS/Cellular/GPS LNA/Mixers
MAX2531/MAX2537/MAX2538 family single- multiband LNA/mixer optimized CDMA, GSM, TDMA applications both cellular bands. addition, MAX2530/MAX2531/MAX2537/MAX2538 feature LNA/mixer signal path E911 traveler assistance applications. cellular signals routed either port. example, port connected filter with 30kHz bandwidth, while other port drive filter with wider bandwidth. band port. optimize dynamic range minimum current, MAX2531/MAX2537/MAX2538 implement multiple mixer states, including high gain/high linearity, high gain/low linearity, midgain, gain, ultra-low gain. high-gain/high-linearity mode, high-IP3 minimizes desensitization presence large interfering signal. other gain states, current reduced improve standby time. Each band implemented with separate mixer optimize performance specific band, each mixer provides multiple linearity modes optimize linearity current consumption. ultra-low gain mode operates with very little current, which results significant power savings because handset typically spends most time this mode.

Detailed Description
Signal Paths Operation Modes
MAX2531/MAX2537/MAX2538 have multiple signal paths. cellular signal path five modes operation using 4-gain-mode 3-gain-mode mixer. Similarly, signal path four modes operation made 2-gain-mode 3-gain-mode mixer. cellular mixer's output routed either port. signal path consists single-mode GPS, LNA, mixer, which dedicated output port. Tables summarize modes operation.
Low-Noise Amplifiers
incorporate three signal paths cellular, PCS, bands. Using Maxim's latest advanced BiCMOS SiGe process, these LNAs deliver noise figure cellular, PCS, bands. cellular band LNAs have four modes operation: high gain/ high linearity (HGHL), high gain/low linearity (HGLL), midgain (MG), gain (LG). band LNAs have modes operation: high gain/high linearity gain. only mode. BAND input selects frequency band. MODE pins logic inputs that control modes (see Table HGHL mode when high

linearity required cross-modulation suppression. HGLL mode when transmitter cross-modulation concern. LNAs designed minimize input VSWR when changing modes. low-gain mode receiving large signals when high sensitivity required. cellular band provides additional gain mode (MG) improved margin CDMA medium-level interference condition.
Applications Information
Cascaded LNA/Mixer Performance
mixer design optimizes cascaded performance gain linearity modes. high-gain/highlinearity mode, both mixer have noise figure, high gain, high linearity. this mode, extra-high linearity superior cross-modulation suppression. high-gain/low-linearity mode used when transmitter cross-modulation concern. ultra-low-gain mode, received signal strong enough that sensitivity limiting factor. This mode focuses minimizing supply current. Tables summarize cascaded performance.
Downconverters
downconverters these devices doublebalanced mixers. cellular mixers have three gain modes: high linearity, linearity, gain. cellular mixers route signal either port. IF_SEL routes signal port; IF_SEL high routes signal port. mixer only mode, dedicated port (Table mixer inputs include on-chip matching networks reduce external component count.
LNAs
inputs require external matching networks optimize gain, linearity, noise figure, return loss. simple match sufficient shown Typical Application Circuit. cellular outputs internally matched. output requires inductor pullup series capacitor external matching elements. Table show Sparameters each LNA. Tables show noise parameters.
Generation
Table shows options generation. on-chip divider multiplier allows triple-band operation with single VCO. MAX2351 MAX2531 have multiplier that doubles cellular band band operation. Conversely, MAX2358, MAX2537, MAX2538 include divider that divides frequency down cellular frequency band. generated fractional frequency scaler, which enables single operation three bands. MAX2530 designed operation with dual-band VCO. buffer output provided phase-locked loop operation. serves functions: output signal phase-locked loop operation logic input enable disable this buffer. logic high applied this enables buffer; logic disables buffer. buffered output provided drive transmit upconverter. controlled BUFFEN input. time-division duplex applications, buffer available drive transmitter even when rest chip shut down. port internally AC-coupled, DCblocking capacitor required.
Mixers
mixer inputs internally matched. mixer inputs require DC-blocking capacitor; cellular mixer does not. outputs must inductively pulled VCC. inductive pullup used part matching network. Because differential output port high impedance, load resistor typically used ease matching establish gain. 3.3k resistor recommended IF1, 8.2k port. equivalent parallel impedance ports typically 12.2k parallel with 0.75pF. Tables show S-parameters mixer input points.

Layout Considerations
Keep signal lines short possible minimize losses radiation. controlled impedance high-frequency traces. high-Q (>40) components input-matching circuit achieve lowest possible noise figure. mixer outputs, keep differential signal lines together equal length ensure signal balance. proper operation, solder exposed paddle evenly ground plane. abundant ground vias between traces minimize undesired coupling.
