The ADMV1128 from Analog Devices is a Microwave Upconverter and Downconverter with an RF Frequency from 24 to 29.5 GHz. It integrates an upconverter (a transmitter), a downconverter (a receiver), and an LO chain with options of a 2x or 4x multiplier in a single chip. This upconverter/downconverter is suitable for use in mmWave 5G, point-to-point radios, radar and electronic warfare systems, and instrumentation & automatic test equipment (ATE).
The upconverters and downconverters offer two modes of frequency translation. One mode is a conversion from and/or to single-ended or complex intermediate frequency (IF) signals, which then pass through an 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 RF receive input, RF transmits 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. It offers a square-law power detector to allow monitoring of the power levels at the mixer inputs of the downconverter.
The ADMV1128 is available in a thermally enhanced, BGA package that measures 6.0 x 6.5 mm. This BGA package enables the ability to heat sink it to the top of the package for the most efficient thermal heat sinking.
