DESCRIPTION
The SA617 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 SA617 is available in 20-lead SSOP package.
The SA617 was designed for portable communication applications
and will function down to 2.7V. The RF section is similar to the
famous SA605. The audio output has an internal amplifier with the
feedback pin accessible. The RSSI output is buffered. The SA617
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.

CIRCUIT DESCRIPTION
The SA617 is an IF signal processing system suitable for second IF
systems with input frequency as high as 150MHz. The bandwidth of
the IF amplifier and limiter is at least 2MHz with 90dB of gain. The
gain/bandwidth distribution is optimized for 455kHz, 1.5k
source
applications. The overall system is well-suited to battery operation
as well as high performance and high quality products of all types.
The input stage is a Gilbert cell mixer with oscillator. Typical mixer
characteristics include a noise figure of 6.2dB, conversion gain of
17dB, and input third-order intercept of 9dBm. The oscillator will
operate in excess of 200MHz in L/C tank configurations. Hartley or
Colpitts circuits can be used up to 100MHz for xtal configurations.
Butler oscillators are recommended for xtal configurations up to
150MHz.
The output impedance of the mixer is a 1.5k
resistor permitting
direct connection to a 455kHz ceramic filter. The input resistance of
the limiting IF amplifiers is also 1.5k
. With most 455kHz ceramic
filters and many crystal filters, no impedance matching network is
necessary. The IF amplifier has 43dB of gain and 5.5MHz
bandwidth. The IF limiter has 60dB of gain and 4.5MHz bandwidth.
To achieve optimum linearity of the log signal strength indicator,
there must be a 12dB(v) insertion loss between the first and second
IF stages. If the IF filter or interstage network does not cause
12dB(v) insertion loss, a fixed or variable resistor or an L pad for
simultaneous loss and impedance matching can be added between
the first IF output (Pin 16) and the interstage network. The overall
gain will then be 90dB with 2MHz bandwidth.
The signal from the second limiting amplifier goes to a Gilbert cell
quadrature detector. One port of the Gilbert cell is internally driven
by the IF. The other output of the IF is AC-coupled to a tuned
quadrature network. This signal, which now has a 90
phase
relationship to the internal signal, drives the other port of the
multiplier cell.
The demodulated output of the quadrature drives an internal op
amp. This op amp can be configured as a unity gain buffer, or for
simultaneous gain, filtering, and 2nd-order temperature
compensation if needed. It can drive an AC load as low as 2k
with
a rail-to-rail output.
A log signal strength completes the circuitry. The output range is
greater than 90dB and is temperature compensated. This log signal
strength indicator exceeds the criteria for AMPs or TACs cellular
telephone. This signal is buffered through an internal unity gain op
amp. The frequency check pin provides a buffered limiter output.
This is useful for implementing an AFC (Automatic Frequency
Check) function. This same output can also be used in conjunction
with limiter output (Pin 11) for demodulating FSK (Frequency Shift
Keying) data. Both pins are of the same amplitude, but 180
out of
phase.
NOTE: Limiter output or Frequency Check output has drive
capability of a load minimum of 2k
or higher to obtain 115mV
output level.
NOTE: dB(v) = 20log V

NOTES:
1. C-message: The C-message and de-emphasis filter combination has a peak gain of 10 for accurate measurements. Without the gain, the
measurements may be affected by the noise of the scope and HP339 analyzer. The de-emphasis filter has a fixed -6dB/Octave slope be-
tween 300Hz and 3kHz.
2. Ceramic filters: The ceramic filters can be 30kHz SFG455A3s made by Murata which have 30kHz IF bandwidth (they come in blue), or
16kHz CFU455Ds, also made by Murata (they come in black). All of our specifications and testing are done with the more wideband filter.
3. RF generator: Set your RF generator at 45.000MHz, use a 1kHz modulation frequency and a 6kHz deviation if you use 16kHz filters, or
8kHz if you use 30kHz filters.
4. Sensitivity: The measured typical sensitivity for 12dB SINAD should be 0.35
V or 116dBm at the RF input.
5. Layout: The layout is very critical in the performance of the receiver. We highly recommend our demo board layout.
6. RSSI: The smallest RSSI voltage (i.e., when no RF input is present and the input is terminated) is a measure of the quality of the layout and
design. If the lowest RSSI voltage is 500mV or higher, it means the receiver is in regenerative mode. In that case, the receiver sensitivity
will be worse than expected.
7. Supply bypass and shielding: All of the inductors, the quad tank, and their shield must be grounded. A 10-15
F or higher value tantalum
capacitor on the supply line is essential. A low frequency ESR screening test on this capacitor will ensure consistent good sensitivity in pro-
duction. A 0.1
F bypass capacitor on the supply pin, and grounded near the 44.545MHz oscillator improves sensitivity by 2-3dB.
8. R5 can be used to bias the oscillator transistor at a higher current for operation above 45MHz. Recommended value is 22k
, but should not
be below 10k
.
