Maxim 公司的MAX2044是高线性2.3-4GHz上/下变换混频器,输入IP3为+32.5dBm,噪音为8.5dB, 2.3-4GHz的转换损耗为7.7dB,可用在2.5GHz WiMAX和LTE 基站,2.7GHz MMDS基站,3.5GHz WiMAX 和LTE基站,固定宽带无线接入,WLL,私人移动无线电和军用系数.本文介绍MAX2044主要特性,方框图, 上/下变换模式元件表以及应用电路图.
The MAX2044 single, high-linearity upconversion/downconversion mixer provides +32.5dBm input IP3, 8.5dB noise figure, and 7.7dB conversion loss for 2300MHz to 4000MHz LTE, WiMAXK, and MMDS wireless infrastructure applications. With an ultra-wide 2600MHz to 4300MHz LO frequency range, the MAX2044 can be used in either low-side or high-side LO injection architectures for virtually all 2.5GHz and 3.5GHz applications.
In addition to offering excellent linearity and noise performance, the MAX2044 also yields a high level of component integration. This device includes a double-balanced passive mixer core, an LO buffer, and on-chip baluns that allow for single-ended RF and LO inputs. The MAX2044 requires a nominal LO drive of 0dBm, and supply current is typically 138mA at VCC = 5.0V or 121mA at VCC = 3.3V.
The MAX2044 is pin similar with the MAX2029/MAX2031 650MHz to 1000MHz mixers and the MAX2039/MAX2041/ MAX2042 1700MHz to 3000MHz mixers, making this entire family of up/downconverters ideal for applications where a common PCB layout is used for multiple frequency bands.
The MAX2044 is available in a compact 20-pin thin QFN (5mm x 5mm) package with an exposed pad. Electrical performance is guaranteed over the extended -40NC to +85NC temperature range.
