2.4GHz Monolithic
Voltage-Controlled Oscillator for Automotive
General Description
The MAX2750AUA is a self-contained voltage-controlled
oscillator (VCO) intended for use over the 2370MHz
to 2470MHz frequency range. The 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 Ω )

CODE
The MAX2750AUA operates over a +2.7V to +5.5V sup-
ply voltage range. Internal regulation of the oscillator sup-
ply voltage eliminates the need for an external LDO
