1. Introduction
The SA58640 was designed for cordless telephone applications in which efficient and
economic integrated solutions are required and yet high performance is desirable.
Although the product is not targeted to meet the stringent specifications of high
performance cellular equipment, it will exceed the needs for analog cordless phones. The
minimal amount of external compone nts and absence of any external adjustments makes
for a very economical solution.

Low-voltage mixer FM IF system
8. Functional description
The SA58640 is an IF signa l pr ocessing system su itable for second IF systems with in put
frequency as high as 100 MHz. The bandwidth of the IF amplifier and limiter is at least
2 MHz with 90 dB of gain. The gain/bandwidth distribution is optimized for 455 kHz,
1.5 kΩ source applications. The overall system is well-suited to battery operation as well
as 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 7.0 dB, conversion gain of 17 dB, and input third-order intercept of
10 dBm. The oscillator will operate in excess of 100 MHz in LC tank configurations.
Hartley or Colpitts circuits can be used up to 100 MHz for crystal configurations.
The output impedance of the mixer is a 1.5 kΩ resistor permitting direct connection to a
455 kHz ceramic filter . The input resist ance of the limiting IF amplifiers is also 1.5 kΩ. With
most 455 kHz ceramic filters and many crystal filters, no impedance matching network is
necessary. The IF amplifier has 44 dB of gain and 5.5 MHz bandwidth. The IF limiter has
58 dB of gain and 4.5 MHz bandwidth. To achieve optimum linearity of the log signal
strength indicator, there must be a 12 dBV1 insertion loss between the first and second IF
stages. If the IF filter or interstage network does not cause 12 dBV 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 90 dB with 2 MHz bandwidth.
The signal from the second limiting amplifier goes to a Gilbert cell qu adrature 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 q uadratu re driv es an internal o p amp. This op amp can be
configured as a unity gain buffer, or for simultaneous gain, filtering, and second-order
temperature compensation if needed. It can drive an AC load as low as 10 kΩ with a
rail-to-rail output.
A log signal strength indicator completes the circuitry. The output range is greater than
70 dB and is temperature compensated. This signal drives an internal op amp. The
op amp is capable of rail-to-rail output. It can be used for gain, filtering, or second-order
temperature compensation of the RSSI, if needed.

[1] The generator source impedance is 50 Ω, but the SA58640 input impedance at pin 18 (IF_AMP_IN) is 1500 Ω. As a result, IF level
refers to the actual signal that enters the SA58640 IF amplifier input (pin 18), which is about 21 dB less than the ‘available power’ at the
generator.

The layout is very critical in the performance of the receiver. We highly recommend our demo board layout.
All of the inductors, the quad tank, and their shield must be grounded. A 10 μF to 15 μF 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
production. A 0.1 μF bypass capacitor on the supply pin VCC, and grounded near the 44.545 MHz oscillator improves sensitivity
by 2 dB to 3 dB.

14. Test information
(1) Set your RF generator at 45.000 MHz, use a 1 kHz modulation frequency and a 6 kHz deviation if
you use 16 kHz filters, or 8 kHz if you use 30 kHz filters.
(2) The measured typical sensitivity for 12 dB SINAD should be 0.45 μV or 11 4 dBm at the RF input.
(3) 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 500 mV or higher, it
means the receiver is in regenerative mode. In that case, the receiver sensitivity will be worse than
expected.
(4) The C-message and de-emphasis filter combination has a peak gain of 10 dB for accurate
measurements. Without the gain, the measurements may be affected by the noise of the scope
and HP339A analyzer . The de-emphasis filter has a fixed 6 dB/octave slope between 300 Hz and
3kHz.

16. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
16.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on on e printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
16.2 Wave and reflow soldering
W ave soldering is a joining te chnology in which the joints are m ade by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
Through-hole components
Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solde r lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads ha ving a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solde rable.
Key characteristics in both wave and reflow soldering are:
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering ve rsus SnPb soldering
16.3 Wave soldering
Key characteristics in wave soldering are:
Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
Solder bath specifications, including temperature and impurities

Low-voltage mixer FM IF system
16.4 Reflow soldering
Key characteristics in reflow soldering are :
Lead-free ve rsus SnPb soldering; note th at a lead-free reflow process usua lly leads to
higher minimum peak temperatures (see Figure 13) than a SnPb process, thus
reducing the process window
Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) an d cooling down. It is imperative that the peak
temperature is high enoug h for the solder to make reliable solder joint s (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of th e package
depends on p ackage thickness and volume and is classified in accordance with
Table 7 and 8
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 13.
