资 源 简 介

Although designed for 1GHz, the SA601 and SA620 can also beused in the 433MHz ISM band. The SA601 performs amplificationof the antenna signal and down conversion to a first IF. The SA620has the same functionality, but also has a VCO on-chip. This VCOdrives the mixer, so no external LO signal is required.Applying the SA601 or SA620 means that a receiver with highsensitivity and wide dynamic range can be built without a lot ofexternal components. The design will be easier compared withdiscrete Front Ends.
