The ADMV1355 is a highly integrated microwave upconverter optimized for wideband radio designs operating in the 17.7GHz to 55GHz RF range. It can be used as a smaller alternative to larger multichip implementations, allowing for reduced size, weight, and power at the system level.

The ADMV1355 has an integrated local oscillator (LO) signal chain that accepts LO input signals in the 8.85GHz to 27.5GHz range. Within the LO signal chain are internal amplifiers, a frequency 2× multiplier, a programmable harmonic reject filter, and phase adjust circuitry, which produces the necessary 17.7GHz to 55GHz signal to drive the internal mixer.

The ADMV1355 offers three mixer modes of frequency translation, single input IF mode, complex input IF mode, and differential I/Q mode. The single input IF mode utilizes one intermediate frequency (IF) input signal, in the 8GHz to 12GHz range, which then pass through an on-chip 90° IF hybrid. The hybrid produces the necessary quadrature signals for the mixer. The complex input IF mode utilizes two quadrature IF input signals, in the 1GHz to 12GHz range. The differential I/Q mode utilizes differential baseband inphase/ quadrature (I/Q) input signals, from DC to 12GHz.
