Manufacturer: NXP Semiconductors.


SA606 datasheet



The SA606 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 SA606 is available in SO20 and SSOP20 packages.

The device was designed for portable communication applications and will function down to 2.7 V. The RF section is similar to the famous SA605. 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.

Let’s take a look at the features of this IC.

1. Low power consumption: 3.5 mA typical at 3 V
2. Mixer input to >150 MHz
3. Mixer conversion power gain of 17 dB at 45 MHz
4. XTAL oscillator effective to 150 MHz
5. 102 dB of IF amp/limiter gain
6. 2 MHz IF amp/limiter small signal bandwidth
7. Temperature compensated logarithmic RSSI with a 90 dB dynamic range
8. Low external component count; suitable for crystal/ceramic/LC filters
7. Audio output internal op amp
8. RSSI output internal op amp
9. Internal op amps with rail-to-rail outputs
10. Latch-up testing is done to JEDEC Standard JESD78 Class II, Level B


1. Portable cellular radio FM IF
2. Cordless phones
3. Wireless systems
4. RF level meter
5. Spectrum analyzer
6. Instrumentation
7. FSK and ASK data receivers
8. Log amps
9. Portable high performance communication receiver
10. Single conversion VHF receivers
