General Description
The MAX2041 high-linearity passive upconverter or downconverter mixer is designed to provide 7.4dB NF and a 7.2dB conversion loss for an RF frequency range of 1700MHz to 3000MHz to support UMTS/WCDMA, DCS, PCS, and WiMAX base-station transmitter or receiver applications. The IIP3 is typically +33.5dBm for both downconversion and upconversion operation. With an LO frequency range of 1900MHz to 3000MHz, this particular mixer is ideal for high-side LO injection architectures. (For a pin-compatible mixer meant for low-side LO injection, refer to the MAX2039.)
In addition to offering excellent linearity and noise perfor­mance, the MAX2041 also yields a high level of compo­nent integration. This device includes a double-balanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also integrated to allow for a single-ended RF input for downconversion (or RF output for upconversion), and single-ended LO inputs. The MAX2041 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 145mA.
The MAX2041 is pin compatible with the MAX2031 815MHz to 995MHz mixer, making this family of passive upconverters and downconverters ideal for applications where a common PC board layout is used for both fre­quency bands.
The MAX2041 is available in a compact 20-pin thin QFN package (5mm x 5mm) with an exposed paddle. Electrical performance is guaranteed over the extended
-40°C to +85°C temperature range.

Note 1: All limits include external component losses. Output measurements taken at IF port for downconverter and RF port for
upconverter from the Typical Application Circuit.
Note 2: Compression point characterized. It is advisable not to continuously operate the mixer RF or IF input above +15dBm. Note 3: Measured with external LO source noise filtered so the noise floor is -174dBm/Hz. This specification reflects the effects of all
SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
Note 4: Refer to the MAX2043 for improved LO leakage of -52dBm typical.

Detailed Description
The MAX2041 can operate either as a downconverter or an upconverter mixer that provides 7.2dB of conver­sion loss with a typical 7.4dB noise figure. IIP3 is +33.5dBm for both upconversion and downconversion operation. The integrated baluns and matching circuitry allow for 50Ω single-ended interfaces to the RF port and two LO ports. The RF port can be used as an input for downconversion or an output for upconversion. A single-pole, double-throw (SPDT) switch provides 50ns switching time between the two LO inputs with 43dB of LO-to-LO isolation. Furthermore, the integrated LO buffer provides a high drive level to the mixer core, reducing the LO drive required at the MAX2041’s inputs to a range of -3dBm to +3dBm. The IF port incor­porates a differential output for downconversion, which is ideal for providing enhanced IIP2 performance. For upconversion, the IF port is a differential input.
Specifications are guaranteed over broad frequency ranges to allow for use in UMTS, cdma2000, 2G/2.5G/3G DCS 1800, PCS 1900, and WiMAX base stations. The MAX2041 is specified to operate over an RF frequency range of 1700MHz to 3000MHz, an LO frequency range of 1900MHz to 3000MHz, and an IF frequency range of DC to 350MHz. Operation beyond these ranges is pos­sible; see the Typical Operating Characteristics for additional details.
This device can operate equally well in low-side LO injec­tion applications as long as the LO frequency range is between 1900MHz and 3000MHz. If an LO frequency range below 1900MHz is desired, refer to the MAX2039.
RF Port and Balun
For using the MAX2041 as a downconverter, the RF input is internally matched to 50Ω, requiring no external match­ing components. A DC-blocking capacitor is required since the input is internally DC shorted to ground through the on-chip balun. The RF return loss is typically better than 17dB over a 1400MHz to 3000MHz frequency range. For upconverter operation, the RF port is a single-ended output similarly matched to 50Ω.
LO Inputs, Buffer, and Balun
The MAX2041 can be used for either high-side or low­side injection applications with a 1900MHz to 3000MHz LO frequency range. For a device with a 1500MHz to 2000MHz LO frequency range, refer to the MAX2039 data sheet. As an added feature, the MAX2041 includes an internal LO SPDT switch that can be used for frequen­cy-hopping applications. The switch selects one of the two single-ended LO ports, allowing the external oscillator to settle on a particular frequency before it is switched in. LO switching time is typically less than 50ns, which is more than adequate for virtually all GSM applications. If frequency hopping is not employed, set the switch to either of the LO inputs. The switch is controlled by a digital input (LOSEL): logic-high selects LO2, logic-low selects LO1. To avoid damage to the part, voltage MUST

be applied to VCCbefore digital logic is applied to LOSEL (see the Absolute Maximum Ratings). LO1 and LO2 inputs are internally matched to 50Ω, requiring only a 22pF DC-blocking capacitor.
A two-stage internal LO buffer allows a wide-input power range for the LO drive. 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 MAX2041 is a double-balanced, high­performance passive mixer. Exceptional linearity is pro­vided by the large LO swing from the on-chip LO buffer.
Differential IF
The MAX2041 mixer has an IF frequency range of DC to 350MHz. Note that these differential ports are ideal for providing enhanced IIP2 performance. Single-ended IF applications require a 1:1 balun to transform the 50Ω dif- ferential IF impedance to a 50Ω single-ended system. After the balun, the IF return loss is better than 15dB. The differential IF is used as an input port for upconvert­er operation. The user can use a differential IF amplifier following the mixer but a DC block is required on both IF pins. In this configuration, the IF+ and IF- pins need to be returned to ground through a high resistance (about 1kΩ). This ground return can also be accomplished by grounding the RF TAP (pin 3) and AC-coupling the IF+ and IF- ports (pins 19 and 18).
Applications Information
Input and Output Matching
The RF and LO inputs are internally matched to 50Ω. No matching components are required. Return loss at the RF port is typically better than 17dB over a 1400MHz to 3000MHz frequency range, and return loss at the LO ports is typically better than 16dB over a 1900MHz to 3000MHz frequency range. RF and LO inputs require only DC-blocking capacitors for interfacing.
The IF output impedance is 50Ω (differential). For eval­uation, an external low-loss 1:1 (impedance ratio) balun transforms this impedance to a 50Ω single-ended out­put (see the Typical Application Circuit).
Bias Resistor
Bias current for the LO buffer is optimized by fine tun­ing resistor R1. If reduced current is required at the expense of performance, contact the factory for details. If the ±1% bias resistor values are not readily available, substitute standard ±5% values.
Layout Considerations
A properly designed PC board is an essential part of any RF/microwave circuit. 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 PC board exposed pad MUST be connected to the ground plane of the PC board. 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 PC board. The MAX2041 Evaluation Kit can be used as a reference for board layout. Gerber files are available upon request at www.maxim-ic.com.
Power-Supply Bypassing
Proper voltage-supply bypassing is essential for high­frequency circuit stability. Bypass each VCCpin and TAP with the capacitors shown in the Typical Application Circuit; see Table 1. Place the TAP bypass capacitor to ground within 100 mils of the TAP pin.
Exposed Pad RF/Thermal Considerations
The EP of the MAX2041’s 20-pin thin QFN-EP package provides a low thermal-resistance path to the die. It is important that the PC board on which the MAX2041 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 PC board, either directly or through an array of plated via holes.
