GENERAL DESCRIPTION
The UAA3220TS is a fully integrated single-chip receiver,
primarily intended for use in VHF and UHF systems.
It supports both Amplitude Shift Keying (ASK) and
Frequency Shift Keying (FSK) demodulation.
By connecting DEMO1 (pin 10) to ground during
realisation of the receiver module the UAA3220TS works
as an ASK receiver (see Fig.10). By connecting pin 10 as
shown in Fig.9 the UAA3220TS works as an FSK receiver.
The UAA3220TS incorporates a crystal stabilized local
oscillator, frequency multiplier, balanced mixer, post mixer
amplifier, limiter, Received Signal Strength Indicator
(RSSI), FSK demodulator, data filter, data slicer and

FUNCTIONAL DESCRIPTION
Mixer
The mixer is a single-balanced emitter-coupled mixer with
internal biasing. Matching of the RF source impedance to
the mixer input requires an external matching network.
Oscillator
The oscillator is based on a transistor connected in
common collector configuration followed by a cascode
stage driving a tuned circuit. The voltage at this tuned
circuit drives the frequency multiplier. The bias current of
the oscillator is set by an off-chip resistor (R40 in the
application diagram of Fig.9) to a typical value of 260 µA at
433.92 MHz (R40 = 1.8 kΩ). The oscillator frequency is
controlled by an off-chip overtone crystal (X40). Off-chip
capacitors between base and emitter (C42) and ground
(C41) make the oscillator transistor appear as having
negative resistance at small signal levels. This causes the
oscillator to start. A parallel resonance circuit (L40 and
C41) connected to the emitter of the oscillator transistor
prevents oscillation at the fundamental frequency of the
crystal. The LC tank circuit at the output of the oscillator is
used to select either the fundamental, the second or the
third harmonic of the oscillator frequency.
Frequency multiplier
UAA3220TS
Limiter
The limiter is a single-ended input multiple stage amplifier
with high total gain. Amplifier stability is achieved by
means of an external DC feedback capacitor (C21), which
is also used to determine the lower limiter cut-off
frequency. An RSSI signal proportional to the limiter input
signal is provided. Figure 3 shows the DC voltage at pin 18
(RSSI) as a function of the input voltage (RMS value) at
pin 20 (LIN). It also gives the typical IF of 10.7 MHz.
The lower knee of the level curve (see Fig.3) is determined
by the effective noise bandwidth and is, consequently,
slightly higher.
IF filter
IF filtering with high selectivity is realized by means of an
external ceramic filter (X20), which feeds the IF from the
PMA to the limiter.
FM demodulator
Coming from the limiter the FSK signal is fed differential to
the input of the FM demodulator. After buffering the signal
is fed to a phase detector. The phase shift is generated by
an external LC combination connected to DEMO1 (pin 10)
and DEMO2 (pin 11). The baseband signal is coupled out
single ended via an output buffer and is fed to the FSK
input of the ASK/FSK switch.
The frequency multiplier is an emitter-coupled transistor
pair driving an off-chip balanced tuned circuit. The bias
current of this emitter coupled pair is set by an off-chip
resistor (R50) to a typical value of 350 µA at 433.92 MHz
(R50 = 1.2 kΩ). The oscillator output signal is AC-coupled
to one of the inputs of the emitter-coupled pair. The other
input is connected to ground via an on-chip capacitor.
The output voltage of the frequency multiplier drives the
switching stage of the mixer. The bias voltage at this point
is set by an off-chip resistor (R51) to allow sufficient
voltage swing at the mixer outputs.
Post mixer amplifier
The Post Mixer Amplifier (PMA) is a differential input,
single-ended output amplifier. Amplifier gain is provided in
order to reduce the influence of the limiter noise figure on
the total noise figure.
ASK/FSK switch
The selection of either ASK or FSK reception will be done
by the DEMO1 (pin 10). Grounding this pin to 0 V will
switch the IC to ASK mode. Additional the FM demodulator
and parts of the data slicer will be switched off. In FSK
mode DEMO1 (pin 10) is connected to DEMO2 (pin 11)
via a LC combination (see Fig.9).
Data filters
After demodulation a two-stage data filtering circuit is
provided in order to suppress unwanted frequency
components. Two RC low-pass filters with on-chip
resistors are provided which are separated by a buffer
stage.

Frequency Shift Keying (FSK)/Amplitude
Shift Keying (ASK) receiver
Data slicer
Data detection is provided by means of a level comparator
with adaptive slice reference. After the first data filter stage
the pre-filtered data is split into two paths. One passes the
second data filter stage and is fed to the positive
comparator input. The other path is fed to an integration
circuit with a large time constant in order to derive the
average value (DC component) as an adaptive slice
reference which is presented to the negative comparator
input. The internal buffer provides 13 dB AC voltage gain.
The adaptive reference allows to detect the received data
over a large range of noise floor levels. The integration
circuit consists of a simple RC low-pass filter with on-chip
resistors. The data slicer output is designed with internal
pull-up.

SOLDERING
Introduction to soldering surface mount packages
This text gives 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
to the printed-circuit board by screen printing, stencilling or
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
for surface 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.
UAA3220TS
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.
• For packages with leads on four sides, the footprint must
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.
