RF2504

VCO/HIGH-ISOLATION BUFFER AMPLIFIER

Typical Applications

• 2-Way Paging

• ISM Band Systems

• Wireless Local Loop Systems

• GPS Receivers

• Cellular Systems

• Low Voltage Applications

Product Description

The RF2504 is an integrated oscillator and buffer ampli-

fier chain designed to achieve extremely low sensitivity to

fluctuations in load impedance and power supply noise,

thereby greatly reducing load pulling and pushing. The IC

offers great flexibility, yet is easy to use. This product was

designed for use in applications with low supply voltages.

It has a power-down feature and is designed to operate

from 700MHz to 1500MHz with the help of an external

resonator. Frequency control is achieved with an external

varactor diode. The IC’s ease of use, reduced load pull-

ing, small size, and low cost make it an ideal LO (Local

Oscillator) for almost any wireless application.
