2.4GHz Monolithic

Voltage-Controlled Oscillators

01/MAX752

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.

♦ On-Chip Tank Circuit

♦ Internally Matched Output Buffer Amplifier

♦ Low-Current Shutdown Mode

♦ +2.7V to +5.5V Supply Voltage Range

♦ Miniature 8-Pin µMAX Package

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.
