RF2504

Preliminary RF2504 VCO/HIGH-ISOLATION BUFFER AMPLIFIER 12 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 amplifier 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 pulling, small size, and low cost make it an ideal LO (Local Oscillator) for almost any wireless application. 0.008 0.004 0.018 0.014 -A- 0.196 0.189 0.050 0.157 0.150 0.244 0.229 Dimensions in mm 0.068 0.053 8° MAX 0° MIN 0.034 0.016 0.009 0.007 NOTES: 1.
