Low voltage high performance mixer FM IF system
Product specification
SA608
DESCRIPTION
The SA608 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 SA608 is available in 20-lead
dual-in-line plastic, 20-lead SOL
(surface-mounted miniature package) and
20-lead SSOP package.
The SA608 was designed for portable
communication applications and will function
down to 2.7V. The RF section is similar to
the famous NE605. The audio output is
buffered. The RSSI output has an internal
amplifier with the feedback pin accessible.
The SA608 also has an extra limiter output.
This signal is buffered from the output of the
limiter and can be used to perform frequency
check. This is accomplished by comparing a
reference frequency with the frequency check
signal using a comparator to a varactor or
PLL at the oscillator inputs.
FEATURES
• Low power consumption: 3.5mA typical at
3V
• Mixer input to >150MHz
• Mixer conversion power gain of 17dB at
45MHz
• XTAL oscillator effective to 150MHz (L.C.
oscillator or external oscillator can be used
at higher frequencies)
• 102dB of IF Amp/Limiter gain
• 2MHz limiter small signal bandwidth
• Temperature compensated logarithmic
Received Signal Strength Indicator (RSSI)
with a 90dB dynamic range
• Low external component count; suitable for
crystal/ceramic/LC filters
• Excellent sensitivity: 0.31µV into 50Ω
matching network for 12dB SINAD (Signal
to Noise and Distortion ratio) for 1kHz tone,
8kHz deviation with RF at 45MHz and IF at
455kHz
• SA608 meets cellular radio specifications
• Audio output internal op amp
• RSSI output internal op amp
• Buffered frequency check output
• Internal op amps with rail-to-rail outputs
• ESD protection: Human Body Model 2kV
Robot Model 200V
