The devices are designed for high linearity and low noise
floor. Their performance on IP3o behavior versus frequency
is very strong. Where other devices show chaotic output,
these devices are almost flat over the frequency range.
Low unadjusted carrier feedthrough, along with the highest
unadjusted sideband suppression available on the market,
results in very stable operation over the entire temperature
range.
Because their RF performance is independent of common
mode voltage, these modulators offer flexible interfacing with
any DAC. This simplifies design-in, improves performance by
retaining the IQ modulator’s output power, and can lower the
bill of materials.
Typical applications place the IQ modulator as part of the
transmit path of a base station, positioned after the DAC and
before the amplifier. After the signals are fed to the I-DAC and
Q-DAC, they are converted to the analog domain. Before the
I and Q signals enter the IQ modulator, they are first low-pass
filtered through a reconstruction filter to remove any aliasing
signals. At the IQ modulator, the signals are up-converted
to RF using an LO signal coming from the PLL/VCO device,
typically referred to as the LO generator.
