RF2506

Preliminary RF2506 VHF/UHF VCO/HIGH-ISOLATION BUFFER AMPLIFIER 12 Typical Applications Low Voltage Wireless LANs IF LO for 2.45GHz ISM Band Systems Wireless Local Loop Digital Cordless Phones Product Description The RF2506 is an integrated oscillator and buffer amplifier chain designed to achieve low sensitivity to fluctuations in load impedance and power supply noise, while maintaining superior phase noise performance. 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 10MHz to 1000MHz 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 wireless applications in the VHF/UHF range. The RF2506 was designed to operate with the 2.4GHz chipset; specifically with the IF portion of the RF2518 PLL/synthesizer.
