产品详情和应用

The ADMV1017 is a silicon germanium (SiGe), microwave, upconverter and downconverter optimized for 5G radio designs operating in the 24 GHz to 29.5 GHz frequency range.

The upconverter offers two modes of frequency translation. The device is capable of direct conversion to radio frequency (RF) from differential baseband I/Q input signals, as well as single-sideband (SSB) upconversion from complex intermediate frequency (IF) inputs. Alternatively, the differential baseband I/Q input path can be disabled and a modulated, single-ended, complex IF signals from 3 GHz to 10.5 GHz can be fed to the IF path. These signals can then be upconverted to 24 GHz to 29.5 GHz while rejecting the unwanted sideband by typically better than 25 dBc. The serial port interface (SPI) provides adjustment of the quadrature phase to allow optimum sideband rejection. In addition, the SPI interface allows powering down the output envelope detector to reduce power consumption when carrier feed through optimization is not necessary.

The downconverter offers two modes of frequency translation. The device is capable of direct quadrature demodulation to differential baseband I/Q output signals, as well as image rejection downconversion to a single-ended complex IF output carrier frequency. The differential baseband outputs can be dc-coupled. More typically, however, the I/Q outputs are ac-coupled with a sufficiently low high-pass corner frequency to ensure adequate demodulation accuracy. The I/Q baseband output common-mode voltage is programmable between 0.75 V and 2.15 V. The SPI interface provides fine adjustment of the quadrature phase to optimize I/Q demodulation performance. Alternatively, the baseband I/Q outputs can be disabled, and the I/Q signals can be passed through an on-chip, active balun to provide two, single-ended, complex IF outputs between 3 GHz and 10.5 GHz.
