General Description
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 50
)
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.
