RF2504 General 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.

RF2510 General Description

The RF2510 is a monolithic integrated circuit intended for use as a low-cost Frequency Synthesizer. The device is provided in a 16 pin SSOP package and is designed to provide a phased locked frequency source for use in local oscillator or transmitter applications. The chip can be used in FM or FSK applications in the U.S. 915MHz ISM band and European 433MHz and 868MHz ISM band. The integrated VCO, dual modulus/dual divide (128/129 or 64/65) pre-scaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked oscillator.
