ADI公司的ADMV1013是24GHz至44GHz 宽带微波升频器,提供两种升频转换模式:从基带 I/Q 直接转换为 RF和从实际 IF 进行单边带升频转换,LO输入频率范围从5.4GHz至10.25 GHz,可实现高达41GHz的LO四倍频器,工作温度−40℃到+85℃,主要用在点对点微波无线电,雷达,电子战争系统,仪表和自动测试设备(ATE).而ADMV1013-EVALZ评估板将ADMV1013与微控制器,低压差(LDO)稳压器和AD5601 nanoDAC®结合在一起,可以快速轻松地评估ADMV1013.微控制器可以让用户通过分析,控制和评估(ACE)软件配置ADMV1013寄存器映射.LDO 稳压器支持由单一电源为 ADMV1013 供电,并提供电源纹波抑制功能.AD5601 nanoDAC让用户在不使用外部电源的情况下衰减来自ADMV1013的混频器的射频(RF)功率.本文介绍了ADMV1013主要特性,功能框图,以及评估板ADMV1013-EVALZ主要特性,配置图,实验室建立图,电路图,材料清单和PCB设计图.

The ADMV1013 is a wideband, microwave upconverter optimized for point to point microwave radio designs operating in the 24 GHz to 44 GHz radio frequency (RF) range.

The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from baseband in-phase quadrature (I/Q) input signals, as well as single-sideband (SSB) upconversion from complex intermediate frequency (IF) inputs. The baseband I/Q input path can be disabled and modulated complex IF signals, anywhere from 0.8 GHz to 6.0 GHz, can be inserted in the IF path and upconverted to 24 GHz to 44 GHz while suppressing the unwanted sideband by typically better than 26 dBc. The serial port interface (SPI) allows adjustment of the quadrature phase and mixer gate voltage to allow optimum sideband suppression and local oscillator (LO) nulling. In addition, the SPI interface allows powering down the output envelope detector to reduce power consumption.

The ADMV1013 upconverter comes in a 40-terminal land grid array package (LGA) package. The ADMV1013 operates over the −40℃ to +85℃ case temperature range.

评估板ADMV1013-EVALZ

The ADMV1013-EVALZ evaluation board incorporates the ADMV1013 with a microcontroller, low dropout (LDO) regulators, and the AD5601 nanoDAC® to allow the quick and easy evaluation of the ADMV1013. The microcontroller allows the user to configure the ADMV1013 register map through the Analysis, Control, Evaluation (ACE) software. The LDO regulators allow the ADMV1013 to be powered on by a single supply, and offer power supply ripple rejection. The AD5601 nanoDAC allows the user to attenuate the radio frequency (RF) power from the mixer of the ADMV1013 without using an external power supply.

The ADMV1013 is a silicon germanium (SiGe) design, wideband, microwave upconverter optimized for point to point microwave radio designs operating in a frequency range of 24 GHz to 44 GHz.

The ADMV1013 comes in a compact, thermally enhanced, 6 mm × 6 mm LGA package, and operates over a temperature range of −40℃ to +85℃. For full details on the ADMV1013, see the ADMV1013 data sheet.
