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.
