2.4GHz Monolithic

Voltage-Controlled Oscillators

General Description

Features

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.

ꢀ Guaranteed Frequency Tuning Range

MAX2750: 2400MHz to 2500MHz (Zero IF)

MAX2751: 2120MHz to 2260MHz

(240MHz to 280MHz IF)

MAX2752: 2025MHz to 2165MHz

(335MHz to 375MHz IF)

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.

Ordering Information

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.
