The MAX2750/MAX2751/MAX2752 are self-contained volt-
age-controlled oscillators (VCOs) intended for use in the
2.4GHz to 2.5GHz ISM band. Each IC combines a fully
integrated oscillator and output buffer in a miniature 8-pin
µMAX package.
The inductor and varactor elements of the tank are inte-
grated on-chip, greatly simplifying application of the part.
The only required external components are a couple of
supply bypass capacitors. The IC provides direct connec-
tion to the VCO tuning voltage input and the VCO buffer
output. The tuning voltage input range is +0.4V to +2.4V,
and the oscillator frequency tuning range is factory adjust-
ed to provide guaranteed limits. The output signal is
buffered by an amplifier stage (internally matched to 50Ω)
to provide higher output power and isolate the device from
load impedance variations.
The MAX2750/MAX2751/MAX2752 operate over a +2.7V
to +5.5V supply voltage range. Internal regulation of the
oscillator supply voltage eliminates the need for an exter-
nal LDO regulator for the VCO. The IC also provides a dig-
itally controlled shutdown mode to permit implementation
of sophisticated power-supply management. In shutdown,
the supply current is reduced to less than 1µA.
