MAX19996A 19-4402 Rev 1 5/09 SiGe, High-Linearity, 2000MHz to 3900MHz Downconversion Mixer with LO Buffer General Description Features The MAX19996A single, high-linearity downconversion 2000MHz to 3900MHz RF Frequency Range mixer provides 8.7dB conversion gain, +24.5dBm IIP3, 2100MHz to 4000MHz LO Frequency Range and 9.8dB noise figure for 2000MHz to 3900MHz WCS, LTE, WiMAX, and MMDS wireless infrastructure appli- 50MHz to 500MHz IF Frequency Range cations. With an ultra-wide LO frequency range of 8.7dB Conversion Gain 2100MHz to 4000MHz, the MAX19996A can be used in either low-side or high-side LO injection architectures 9.8dB Noise Figure for virtually all 2.5GHz and 3.5GHz applications. For a +24.5dBm Typical Input IP3 2.5GHz variant tuned specifically for low-side injection, refer to the MAX19996 data sheet. 11dBm Typical Input 1dB Compression Point In addition to offering excellent linearity and noise 67dBc Typical 2LO-2RF Spurious Rejection at performance, the MAX19996A also yields a high level P = -10dBm RF of component integration. This device includes a dou- ble-balanced passive mixer core, an IF amplifier, and Integrated LO Buffer an LO buffer. On-chip baluns are also integrated to Integrated RF and LO Baluns for Single-Ended allow for single-ended RF and LO inputs. The Inputs MAX19996A requires a nominal LO drive of 0dBm, and supply current is typically 230mA at V = 5.0V, CC Low -3dBm to +3dBm LO Drive or 150mA at V = 3.3V. CC Pin Compatible with the MAX19996 2000MHz to The MAX19996A is pin compatible with the MAX19996 3000MHz Mixer 2000MHz to 3000MHz mixer. The device is also pin similar with the MAX9984/MAX9986/MAX9986A Pin Similar with the MAX9993/MAX9994/MAX9996 400MHz to 1000MHz mixers and the MAX9993/ Series of 1700MHz to 2200MHz Mixers and the MAX9994/MAX9996 1700MHz to 2200MHz mixers, MAX9984/MAX9986/MAX9986A Series of 400MHz making this entire family of downconverters ideal for to 1000MHz Mixers applications where a common PCB layout is used for Single 5.0V or 3.3V Supply multiple frequency bands. External Current-Setting Resistors Provide Option The MAX19996A is available in a compact 5mm x 5mm, 20-pin thin QFN with an exposed pad. Electrical perfor- for Operating Device in Reduced-Power/Reduced- mance is guaranteed over the extended -40C to Performance Mode +85C temperature range.

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. 5.0V SUPPLY DC ELECTRICAL CHARACTERISTICS (Typical Application Circuit, V = 4.75V to 5.25V, no input AC signals.
