The ADMV1455 is a highly integrated microwave downconverter
optimized for wideband radio designs operating in the 17.7GHz
to 55GHz RF frequency range. Provides a compact alternative to
traditional multichip solutions, significantly reducing system size,
weight, and power consumption.
The integrated local oscillator (LO) signal chain accepts LO input
signals in the 8.85GHz to 27.5GHz range. In the LO signal chain,
there are internal amplifiers, a 2× frequency multiplier, programmable
harmonic-rejection filters, and phase-adjust circuitry that generates
the necessary 17.7GHz to 55GHz signal to drive the in-phase/
quadrature (I/Q) mixer.
The ADMV1455 has two, switch selectable, RF signal chains. One
chain operates within the 17.7GHz to 34GHz range, and the other
chain operates in the 30GHz to 55GHz range. Each chain has
multiple stages of low noise amplifiers (LNAs), signal level control,
and filtering. A power detector is provided to allow monitoring of the
power levels at the I/Q mixer inputs.
The two frequency translation modes available are: a single-ended
output intermediate frequency (IF) and a differential I/Q baseband.
The single-ended output IF mode operates in the 2GHz to 12GHz
frequency range and includes an on-chip 90° IF hybrid, a tunable
filter, and two adjustable stages of gain control. The differential
I/Q baseband mode operates from DC to 8GHz and includes a programmable
internal common-mode voltage, programmable offset
voltages, and programmable gain select. The differential output
impedance is centered about 75Ω, which allows the baseband
outputs to interface with either a 50Ω or 100Ω differential load
impedance.
