SA605 Datasheet (NXP) - High performance low power mixer FM IF system

SA605, High performance low power mixer FM IF system

The SA605 is a high performance monolithic low-power FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, muting, logarithmic received signal strength indicator (RSSI), and voltage regulator.

The SA605 combines the functions of NXP SA602
