SA606
Low-voltage high performance mixer FM IF system
Rev. 6 — 8 November 2013
Product data sheet
1. General description
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 SA606 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.
2. Features and benefits
Low power consumption: 3.5 mA typical at 3 V
Mixer input to >150 MHz
Mixer conversion power gain of 17 dB at 45 MHz
XTAL oscillator effective to 150 MHz (LC oscillator or external oscillator can be used at
higher frequencies)
102 dB of IF amp/limiter gain
2 MHz IF amp/limiter small signal bandwidth
Temperature compensated logarithmic RSSI with a 90 dB dynamic range
Low external component count; suitable for crystal/ceramic/LC filters
Excellent sensitivity: 0.31
V
into 50
matching network for 12 dB SINAD
(Signal-to-Noise-and-Distortion ratio) for 1 kHz tone with RF at 45 MHz and IF at
455 kHz
SA606 meets cellular radio specifications
Audio output internal op amp
RSSI output internal op amp
Internal op amps with rail-to-rail outputs
ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per
JESD22-C101
Latch-up testing is done to JEDEC Standard JESD78 Class II, Level B
