MAX2051 19-4582 Rev 0 4/09 SiGe, High-Linearity, 850MHz to 1550MHz Up/Downconversion Mixer with LO Buffer General Description Features The MAX2051 high-linearity, up/downconversion mixer 850MHz to 1550MHz RF Frequency Range provides +35dBm input IP3, 7.8dB noise figure (NF), and 1200MHz to 2250MHz LO Frequency Range 7.4dB conversion loss for 850MHz to 1550MHz wireless infrastructure and multicarrier cable head-end down- 50MHz to 1000MHz IF Frequency Range stream video, video-on-demand (VOD), and cable DOCSIS 3.0 and Euro DOCSIS Compatible modem termination systems (CMTS) applications. The MAX2051 also provides excellent suppression of spuri- 7.4dB Typical Conversion Loss ous intermodulation products (> 77dBc at an RF level of 7.8dB Typical Noise Figure -14dBm), making it an ideal downconverter for DOCSIS 3.0 and Euro DOCSIS cable head-end systems. With an +24dBm Typical Input 1dB Compression Point LO circuit tuned to support frequencies ranging from +35dBm Typical Input IP3 1200MHz to 2250MHz, the MAX2051 is ideal for high- side LO injection applications over an IF frequency 88dBc Typical 2RF-LO Rejection at P = -14dBm RF range of 50MHz to 1000MHz. Integrated LO Buffer In addition to offering excellent linearity and noise per- formance, the MAX2051 also yields a high level of com- Integrated RF and LO Baluns for Single-Ended Inputs ponent integration. The device integrates baluns in the Low LO Drive (0dBm Nominal) RF and LO ports, which allow for a single-ended RF input and a single-ended LO input. The MAX2051 External Current-Setting Resistor Provides Option requires a typical LO drive of 0dBm and a supply cur- for Operating Device in Reduced-Power/ rent guaranteed to below 130mA. Reduced-Performance Mode The MAX2051 is available in a compact 5mm x 5mm, 20-pin thin QFN package with an exposed pad. Ordering Information Electrical performance is guaranteed over the extended temperature range, from T = -40C to +85C.

This formula can be used when the temperature of the exposed J C JC CC CC 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 +150C. Note 2: Junction temperature T = T + ( x V x I ). This formula can be used when the ambient temperature of the PCB is J A JA CC CC known. The junction temperature must not exceed +150C. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four- layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Note 4: T is the temperature on the exposed pad of the package. T is the ambient temperature of the device and PCB. C A 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.
