1、Maxim MAX2044 2. 3-4GH z上下变换混频方案Maxim公司的MAX2044是高线性2. 3-4GHz上/下变换混频器,输入1P3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-1inearity upconversion/down

2、conversion 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 L0 frequency range, the MAX2044 can be used in either low-side or high- side LO inje

3、ction architectures for virtual 1y all 2. 5GHz and 3.5GHz applications.In addition to offering excel lent linearity and noise performance, the MAX2044 also yields a high level of component integration. This device includes a double-balanced passive mixer core, an L0 buffer, and on-chip baluns that a

4、llow for single-ended RF and L0 inputs. The MAX2044 requires a nominal L0 drive of OdBm, 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 mixer

5、s, 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
