FUNCTIONAL DESCRIPTION

The RF signal is fed directly into the mixer stage where it
is mixed down to nominal 500 kHz IF by the integrated
oscillator controlledby anexternalSAWR (seeFig.1). The
IF signalisthenpassedtotheIF amplifierwhichincreases
the level. A 5th-order elliptic low-pass filter acts as main
IF filtering. The output voltage of that filter is demodulated
by a limiter that rectifies the incoming IF signal. The
demodulated signal passes two RC filter stages and is
thenlimited by a data comparator which makes it available
at the data output.

Mixer

The mixer is a single balanced emitter coupled pair with
internally set bias current. The optimum impedance is
320 Ω at 430 MHz. Capacitor C5 (see Fig.9) is used to
transform a 50 Ω generator impedance to the optimum
value.

Oscillator

The oscillator consists of a transistor in common base
configuration and a tank circuit including the SAWR.
Resistor R2 (see Fig.9) is used to control the bias current
through the transistor. Resistor R3 is required to reduce
unwanted responses of the tank circuit.

IF amplifier

The IF amplifier is a differential input, single-ended output
emitter coupled pair. It is used to decouple the first and the
second IF filter and to provide some additional gain in
order to reduce the influence of the noise of the limiter on
the total noise figure.

IF filters

The first IF filter is an RC filter formed by internal resistors
and an external capacitor C7 (see Fig.1).

The second IF filter is an external elliptic filter. The source
impedance is 1.4 kΩ and the load is high-impedance. The
bandwidth of the IF filter in the application and test circuit
(see Fig.9) is 800 kHz due to the centre frequency spread
of the SAWR. It may be reduced when SAWRs with less
tolerances are used or temperature range requirements
are lower. A smaller bandwidth of the filter will yield a
higher sensitivity of the receiver. As the RF signal is mixed
down to a low IF signal there is no image rejection
possible.

Limiter

The limiting amplifier consists of three DC coupled
amplifier stages with a total gain of 60 dB. A Received
Signal Strength Indicator (RSSI) signal is generated by
rectifying the IF signal. The limiter has a lower frequency
limitof 100 kHz which can be controlled by capacitors C12
and C19. The upper frequency limit is 3 MHz.

Comparator

The2 × IF component in the RSSI signalisremoved by the
first order low-pass capacitor C17. After passing a buffer
stage the signal is split into two paths, leading via
RC filters to the inputs of a voltage comparator. The time
constant of one path (C14) is compared to the bit duration.
Consequently the potential at the negative comparator
input represents the average magnitude of the RSSI
signal. The second path with a short time constant (C13)
allows the signal at the positive comparator input to follow
the RSSI signal instantaneously. This results in a variable
comparator threshold, depending on the strength of the
incoming signal. Hence the comparator output is switched
on, when the RSSI signal exceeds its average value, i.e.
when an ASK ‘on’ signal is received.

The low-pass filter capacitor C13 rejects the unwanted
2 × IF component and reduces the noise bandwidth of the
data filter.

The resistor R1 is used to set the current of an internal
source. This current is drawn from the positive comparator
input,therebyapplyinganoffsetanddriving the output into
the ‘off’ state during the absence of an input signal. This
offset can be increased by lowering the value of R1
yieldinga higher noise immunity at the expenseofreduced
sensitivity.

Band gap reference

The band gap reference controls the biasing of the whole
circuit. In this block currents are generated that are
constant over the temperature range and currents that are
proportional to the absolute temperature.

The current consumption of the receiver rises with
increasing temperature, because the blocks with the
highest current consumption are biased by currents that
are proportional to the absolute temperature.

SOLDERING
Introduction to soldering surface mount packages

Thistextgives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.

Reflow soldering

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
totheprinted-circuitboardbyscreenprinting,stencillingor
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.

Wave soldering

Conventional single wave soldering is not recommended
forsurface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

If wave soldering is used the following conditions must be
observed for optimal results:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

• Forpackages with leads on four sides, thefootprintmust
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Manual soldering

Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.

When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Suitability of surface mount IC packages for wave and reflow soldering methods

Notes

1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

.

2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).

3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.

4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.

5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
