The ADMV1139A is a silicon on isolator (SOI), microwave, upconverter and downconverter optimized for 5G radio designs operating in the 37 GHz to 50 GHz frequency range.
Both upconverters and downconverters offer two modes of frequency translation. One mode is conversion from and/or to complex intermediate frequency (IF) signals, which then pass through an optional on-chip 90° IF hybrid, known as IF mode.
The other mode is a direct conversion from and/or to differential baseband inphase/quadrature (I/Q) inputs and
outputs, known as baseband mode. The I/Q baseband output common-mode voltage is programmable between 0.7 V and 1.5 V.
When the device is used as an image rejecting downconverter, the unwanted image term is typically rejected to 26 dBc, before calibration. The ADMV1139A offers a square law power detector to allow monitoring of the power levels at the mixer inputs of the downconverter.
The RF receive input, RF transmit output, and local oscillator (LO) interface are all single-ended and matched to 50 Ω. The on-chip RF switch provides the option to combine the transmit and receive RF ports together for time division duplex (TDD) applications.
The serial port interface (SPI) provides adjustment of the LO chain I/Q phase to allow optimum sideband rejection. In addition, the SPI allows powering down the output envelope detector to reduce power consumption when carrier feedthrough optimization is not necessary.
The ADMV1139A upconverter and downconverter is housed in a compact, thermally enhanced, 6 mm × 6.5 mm, ball grid array (BGA) package. This BGA package enables the ability to heat sink the ADMV1139A from the top of the package for the most efficient thermal heat sinking. The ADMV1139A operates over the −40°C to +95°C TC range.
