Overview
The SA605D/01,112 is a high-performance monolithic low-power FM IF (Intermediate Frequency) system manufactured by NXP USA Inc. 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 combines the functions of the NXP SA602A and SA604A but offers enhanced performance with a higher mixer input intercept point, higher IF bandwidth, and temperature-compensated RSSI and limiters. The SA605D is available in a 20-lead SO (surface-mounted miniature package) and is designed for various high-performance communication and radio applications.
