Electrical performance is guaranteed over the extended -40NC to +85NC temperature range. S S IF- The MAX2042 is pin compatible with the MAX2042A 2000MHz to 3900MHz mixer. The device is also pin similar with the MAX2029/MAX2031 650MHz to 1000MHz mixers, the MAX2039/MAX2041 1700MHz to 3000MHz mixers, and the MAX2044/MAX2044A 3000MHz to 4000MHz mixers, making this entire family of up/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands.

This device includes a doublebalanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The MAX2042 requires a nominal LO drive of 0dBm, and supply current is typically 138mA at VCC = +5.0V or 120mA at VCC = +3.3V. S S S S S S S S GND The MAX2042 single, high-linearity upconversion/downconversion mixer provides +36dBm IIP3, 7.3dB noise figure, and 7.2dB conversion loss for 2000MHz to 3000MHz WCS, LTE, WiMAXK, and MMDS wireless infrastructure applications. With a wide LO frequency range of 1800MHz to 2800MHz, this particular mixer is ideal for low-side LO injection receiver and transmitter architectures. High-side LO injection is supported by the MAX2042A, which is pinpin and functionally compatible with the MAX2042.

This formula can be used when the temperature of the exposed pad is known while the device is soldered down to a PCB. See the Applications Information section for details. The junction temperature must not exceed +150NC. Note 2: Junction temperature TJ = TA + (BJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is known. The junction temperature must not exceed +150NC. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a fourlayer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Note 4: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. +5.0V SUPPLY DC ELECTRICAL CHARACTERISTICS (Typical Application Circuit, VCC = +4.75V to +5.25V, no input AC signals.

The integrated baluns and matching circuitry allow for 50I single-ended interfaces to the RF and the LO ports. The integrated LO buffer provides a high drive level to the mixer core, reducing the LO drive required at the MAX2042's input to a -3dBm to +3dBm range. The IF port incorporates a differential interface, which is ideal for providing enhanced 2RF - 2LO performance. Specifications are guaranteed over broad frequency ranges to allow for use in WCS, LTE, WiMAX, and MMDS base stations. The MAX2042 is specified to operate over an RF input range of 2000MHz to 3000MHz, an LO range of 1800MHz to 2800MHz, and an IF range of 50MHz to 500MHz. The external IF transformer sets the lower frequency range (see the Typical Operating Characteristics for details). Operation beyond these ranges is possible (see the Typical Operating Characteristics for additional information). RF Interface and Balun The MAX2042 RF input provides a 50I match when combined with a series DC-blocking capacitor. This DC-blocking capacitor required as the input is internally DC shorted to ground through the on-chip balun. When using an 8.2pF DC-blocking capacitor, the RF port input return loss is typically 15dB over the RF frequency range of 2500MHz to 2900MHz. LO Inputs, Buffer, and Balun The MAX2042 is optimized for low-side LO injection applications with an 1800MHz to 2800MHz LO frequency range. The LO input is internally matched to 50I, requiring only a 2pF DC-blocking capacitor. A two-stage internal LO buffer allows for a -3dBm to +3dBm LO input power range. The on-chip low-loss balun, along with an LO buffer, drives the double-balanced mixer. All interfacing and matching components from the LO inputs to the IF outputs are integrated on-chip. High-Linearity Mixer The core of the MAX2042 is a double-balanced, highperformance passive mixer. Exceptional linearity is provided by the large LO swing from the on-chip LO buffer. IIP3, 2RF - 2LO rejection, and noise-figure performance are typically +36dBm, 70dBc, and 7.3dB, respectively. Differential IF Interface The MAX2042 has an IF frequency range of 50MHz to 500MHz, where the low-end frequency depends on the frequency response of the external IF components. The MAX2042's differential ports are ideal for providing enhanced 2RF - 2LO performance. The user can use a differential IF amplifier or SAW filter on the mixer IF port, but a DC block is required on both IF+/IF- ports to keep external DC from entering the IF ports of the mixer. Typical applications typically use a 1:1 transformer such as the MABAES0029 to transform the 50I differential interface to a 50I single-ended interface. The loss of this transformer is included in the data presented in this data sheet. In addition, the IF interface directly supports single-ended AC-coupled signals into or out of IF+ by shorting IF- to ground, and a 1kI resistor from IF+ to ground. Applications Information Input and Output Matching The RF input provides a 50I match when combined with a series DC-blocking capacitor. Use an 8.2pF capacitor value for RF frequencies ranging from 2000MHz to 3000MHz. The LO input is internally matched to 50I; use a 2pF DC-blocking capacitor to cover operations spanning the 1800MHz to 2800MHz range. The IF output impedance is 50I (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun transforms this impedance down to a 50I single-ended output (see the Typical Application Circuit). Reduced-Power Mode The MAX2042 has one pin (LOBIAS) that allows an external resistor to set the internal bias current. A nominal value for this resistor is shown in Tables 1 and 2. Larger value resistors can be used to reduce power dissipation at the expense of some performance loss. See the Typical Operating Characteristics to evaluate the power vs. performance tradeoff. If Q1% resistors are not readily available, substitute with Q5% resistors. Significant reductions in power consumption can also be realized by operating the mixer with an optional supply voltage of +3.3V. Doing so reduces the overall power consumption by up to 43%. See the +3.3V Supply AC Electrical Characteristics table and the relevant +3.3V curves in the Typical Operating Characteristics section to evaluate the power vs. performance tradeoffs. 24 SiGe High-Linearity, 2000MHz to 3000MHz Upconversion/Downconversion Mixer with LO Buffer Power-Supply Bypassing Proper voltage-supply bypassing is essential for highfrequency circuit stability. Bypass each VCC pin with the capacitors shown in the Typical Application Circuit and see Tables 1 and 2. Exposed Pad RF/Thermal Considerations The exposed pad (EP) of the MAX2042's 20-pin thin QFN package provides a low thermal-resistance path to the die. It is important that the PCB on which the MAX2042 is mounted be designed to conduct heat from the EP. In addition, provide the EP with a low-inductance path to electrical ground. The EP MUST be soldered to a ground plane on the PCB, either directly or through an array of plated via holes. Table 1.

Keep RF signal lines as short as possible to reduce losses, radiation, and inductance. For the best performance, route the ground pin traces directly to the exposed pad under the package. The PCB exposed pad MUST be connected to the ground plane of the PCB. It is suggested that multiple vias be used to connect this pad to the lower-level ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed pad on the bottom of the device package to the PCB.
