Fast Start-Up Oscillator (FOX) Boosts Superhet Performance


Abstract: Maxim has incorporated a unique fast-start oscillator system in the single-chip superheterodyne RF receiver devices. Targeted for applications in the 300MHz to 450MHz ISM (US) band, the receivers conserve battery power by reducing startup time of the receiver. The fast-start oscillator circuit enables lower duty cycles for receiver scanning.
