Product Details
The ADMV1018 is a silicon germanium (SiGe), microwave, upconverter and downconverter optimized for 5G radio designs operating in the 24.0 GHz to 29.5 GHz frequency range.
The upconverter offers two modes of frequency translation. The device is capable of direct conversion to RF from differential baseband inphase/quadrature (I/Q) input signals, as well as single-sideband upconversion from complex intermediate frequency (IF) inputs. The differential baseband I/Q input path can be disabled, and modulated, single-ended, complex IF signals from 2 GHz to 9.5 GHz can be fed to the IF path. These signals can then be upconverted to 24.0 GHz to 29.5 GHz while rejecting the unwanted sideband by typically greater 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 feedthrough 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 I/Q baseband output common-mode voltage is programmable between 0.75 V and 2.15 V. The SPI 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 2 GHz and 9.5 GHz. When the device is used as an image rejecting downconverter, the unwanted image term is typically rejected to greater than 25 dBc. The ADMV1018 offers a square law power detector to allow monitoring of the power levels at the mixer inputs. The detector output provides closed-loop control of the RF digital step attenuator (DSA) via an external automatic gain control (AGC) loop.
The ADMV1018 upconverter and downconverter is housed in a compact, thermally enhanced, 9 mm × 8 mm, land grid array (LGA) package. This LGA package enables the ability to heat-sink the ADMV1018 from the top of the package for the most efficient thermal heatsinking. The ADMV1018 operates over the −40°C to +95°C case temperature range.
