Philips Semiconductors is dedicated to playing a major role in the wireless communication market. Key to this goal is Philips’ commitment for design assistance at all levels. This is the purpose of the SA601/SA606 combo-board. The SA601 is a combined RF amplifier and mixer designed for high-performance low-power communication systems from 800-1200MHz. The SA606 is a low-voltage high performance monolithic FM IF system that, when combined with the SA601, results in a high performance double down-conversion FM receiver. To better support this type of application, Philips has combined the SA601 and SA606 ICs onto a single board which highlights how well the SA601 and the SA606 work together. This application note explains how to overcome many of the technical problems that might arise, and shows how to achieve the best possible performance from the SA601 and SA606. Test results are also included.
