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.

評估板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.
