19-2487; Rev 3; 1/04 Quadruple-Mode PCS/Cellular/GPS LNA/Mixers The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/ MAX2531/MAX2537/MAX2538 family of single- and multiband LNA/mixer ICs is optimized for CDMA, GSM, and TDMA applications in both cellular and PCS bands. In addition, the MAX2530/MAX2531/MAX2537/MAX2538 ICs feature a GPS LNA/mixer signal path for E911 and traveler assistance applications. The cellular and PCS signals can be routed to either IF port. For example, one IF port can be connected to an IF filter with 30kHz bandwidth, while the other port can drive an IF filter with a wider bandwidth. The GPS band has its own IF port. To optimize dynamic range at minimum current, the MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/ MAX2531/MAX2537/MAX2538 implement multiple LNA and mixer states, including high gain/high linearity, high gain/low linearity, midgain, low gain, and ultra-low gain. In high-gain/high-linearity mode, the high-IP3 LNA minimizes desensitization in the presence of a large interfering signal. For the other gain states, the LNA current is reduced to improve standby time. Each band is implemented with a separate mixer to optimize performance for the specific band, and each mixer provides multiple linearity modes to optimize linearity and current consumption. The ultra-low gain mode operates with very little current, which results in significant power savings because the handset typically spends most of its time in this mode.

Exposed Detailed Description Signal Paths and Operation Modes The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/ MAX2531/MAX2537/MAX2538 have multiple RF signal paths. The cellular signal path has five modes of operation using a 4-gain-mode LNA and a 3-gain-mode mixer. Similarly, the PCS signal path has four modes of operation made up of a 2-gain-mode LNA and a 3-gain-mode mixer. The cellular and PCS mixer’s IF output can be routed to either the IF0 or IF1 port. The GPS signal path consists of a single-mode GPS, LNA, and mixer, which has a dedicated IF output port. Tables 1 and 2 summarize the modes of operation. Exposed Pad. RF and DC ground. Low-Noise Amplifiers The MAX2351/MAX2358/MAX2530/MAX2531/MAX2538 incorporate three LNA signal paths for the cellular, PCS, and GPS bands. Using Maxim’s latest advanced BiCMOS SiGe process, these LNAs deliver 1dB noise figure for cellular, PCS, and GPS bands. The cellular band LNAs have four modes of operation: high gain/ high linearity (HGHL), high gain/low linearity (HGLL), midgain (MG), and low gain (LG). The PCS band LNAs have two modes of operation: high gain/high linearity and low gain. The GPS LNA has only one mode. The BAND input selects the frequency band. The G1, G2, and MODE pins are logic inputs that control the LNA modes (see Table 2). Use HGHL mode when high _______________________________________________________________________________________ 9 MAX2351/4/8/9/MAX2530/1/7/8 Pin Description (continued) MAX2351/4/8/9/MAX2530/1/7/8 Quadruple-Mode PCS/Cellular/GPS LNA/Mixers LNA linearity is required for cross-modulation suppression. Use HGLL mode when the transmitter is off and cross-modulation is not a concern. The LNAs are designed to minimize input VSWR when changing modes. Use low-gain mode for receiving large signals and when high sensitivity is not required. The cellular band provides an additional gain mode (MG) for improved IP3 margin in CDMA medium-level interference condition. Downconverters The downconverters in these devices are doublebalanced mixers. The cellular and PCS mixers have three gain modes: high linearity, low linearity, and low gain. The cellular and PCS mixers can route the IF signal to either IF0 or IF1 port. IF_SEL = low routes the IF signal to IF0 port; IF_SEL = high routes the IF signal to IF1 port. The GPS mixer has only one mode, and it has a dedicated IF port (Table 2). All mixer inputs include on-chip matching networks to reduce the external component count. LO Generation Table 3 shows the options for the LO generation. The on-chip LO divider or multiplier allows triple-band operation with a single VCO. The MAX2351 and MAX2531 have an LO multiplier that doubles the cellular band VCO for PCS band operation. Conversely, the MAX2358, MAX2537, and MAX2538 include an LO divider that divides the PCS VCO frequency down to cellular frequency band. The GPS LO is generated by a fractional frequency scaler, which enables a single VCO for operation in all three bands. The MAX2530 is designed for operation with a dual-band VCO. The PLL buffer output is provided for phase-locked loop operation. The PLL pin serves two functions: RF output signal for phase-locked loop operation and logic input to enable or disable this buffer. A logic high applied to this pin enables the PLL buffer; a logic low disables the buffer. A buffered LO output is provided to drive a transmit upconverter. It is controlled by the BUFFEN input. For time-division duplex applications, the buffer is available to drive the transmitter even when the rest of the chip is shut down. The port is internally AC-coupled, so a DCblocking capacitor is not required. Bias Control The bias control input (BIAS pin) controls the IC bias current. Typically, connect a 20kΩ resistor to ground for normal operation. Smaller bias resistor values increase the supply current and linearity. 10 Applications Information Cascaded LNA/Mixer Performance The LNA and mixer design optimizes cascaded performance in all gain and linearity modes. In high-gain/highlinearity mode, both the LNA and mixer have low noise figure, high gain, and high linearity. In this mode, the LNA has extra-high linearity for superior cross-modulation suppression. The high-gain/low-linearity mode is used when the transmitter is off and cross-modulation is not a concern. In the ultra-low-gain mode, the received signal is strong enough that sensitivity is not the limiting factor. This mode focuses on minimizing supply current. Tables 4, 5, 6 summarize the cascaded performance. LNAs The LNA inputs require external matching networks to optimize gain, linearity, noise figure, and return loss. A simple LC match is sufficient as shown in the Typical Application Circuit. The cellular and GPS LNA outputs are internally matched. The PCS LNA output requires an inductor pullup to VCC and a series capacitor as external matching elements. Table 7, 8, 9 show the Sparameters for each LNA. Tables 13, 14, 15 show LNA noise parameters. Mixers All mixer inputs are internally matched. The GPS and PCS mixer inputs require a DC-blocking capacitor; the cellular mixer does not. All IF outputs must be inductively pulled up to VCC. The inductive pullup may be used as part of the matching network. Because the differential IF output port is high impedance, a load resistor is typically used to ease the matching and establish the gain. A 3.3kΩ resistor is recommended for IF0 and IF1, and 8.2kΩ for the GIF port. The equivalent parallel RC impedance of the IF ports is typically 12.2kΩ in parallel with 0.75pF. Tables 10, 11, 12 show S-parameters for the mixer input points. Table 1.

These tanks are coupled by an external L-C network between pins 8 and 10 as shown in the Typical Application Circuit. Keep RF signal lines as short as possible to minimize losses and radiation. Use controlled impedance on all high-frequency traces. Use high-Q (>40) components for the LNA input-matching circuit to achieve the lowest possible noise figure. At the mixer outputs, keep the differential signal lines together and of equal length to ensure signal balance. For proper operation, solder the exposed paddle evenly to the ground plane. Use abundant ground vias between RF traces to minimize undesired coupling. ______________________________________________________________________________________ 11 MAX2351/4/8/9/MAX2530/1/7/8 Table 2.
