MAX19996 19-4177 Rev 0 7/08 SiGe High-Linearity, 2000MHz to 3000MHz Downconversion Mixer with LO Buffer General Description Features The MAX19996 single, high-linearity downconversion 2000MHz to 3000MHz RF Frequency Range mixer provides 8.7dB conversion gain, +24.5dBm IIP3, 1800MHz to 2550MHz LO Frequency Range and 9.6dB noise figure for 2000MHz to 3000MHz WCS, LTE, WiMAX, and MMDS wireless infrastructure appli- 50MHz to 500MHz IF Frequency Range cations. With an 1800MHz to 2550MHz LO frequency 8.7dB Typical Conversion Gain range, this particular mixer is ideal for low-side LO injection receiver architectures. High-side LO injection 9.6dB Typical Noise Figure is supported by the MAX19996A, which is pin-for-pin +24.5dBm Typical Input IP3 and functionally compatible with the MAX19996. +11dBm Typical Input 1dB Compression Point In addition to offering excellent linearity and noise perfor- mance, the MAX19996 also yields a high level of compo- 69dBc Typical 2RF-2LO Spurious Rejection at nent integration. This device includes a double-balanced P = -10dBm RF passive mixer core, an IF amplifier, and an LO buffer. Integrated LO Buffer On-chip baluns are also integrated to allow for single- ended RF and LO inputs. The MAX19996 requires a Integrated RF and LO Baluns for Single-Ended nominal LO drive of 0dBm, and supply current is typical- Inputs ly 230mA at V = +5.0V or 149.5mA at V = +3.3V.

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.
