Product Summary
The SA616DK01-T is a low-voltage high performance monolithic FM IF system incorporating a mixer/oscillator, two limiting intermediate frequency amplifiers, quadrature detector, logarithmic received signal strength indicator (RSSI), voltage regulator and audio and RSSI op amps. The SA616DK01-T is available in 20-lead SSOP (shrink small outline package). The SA616DK01-T is designed for portable communication applications and will function down to 2.7V. The audio and RSSI outputs have amplifiers with
access to the feedback path. This enables the designer to adjust the output levels or add filtering. Applications of the SA616DK01-T include Portable cellular radio FM IF, Cordless phones, Wireless systems, RF level meter, Spectrum analyzer, Instrumentation, FSK and ASK data receivers, Log amps, Portable high performance communication receiver and Single conversion VHF receivers.
