Overview
The SA605DK/01,112 is a high-performance monolithic low-power FM IF system produced by NXP Semiconductors. This component integrates a mixer/oscillator, two limiting intermediate frequency amplifiers, a quadrature detector, muting, a logarithmic received signal strength indicator (RSSI), and a voltage regulator. It is designed to combine the functions of the NXP SA602A and SA604A, offering enhanced performance with a higher mixer input intercept point, higher IF bandwidth, and temperature-compensated RSSI and limiters.
