GSM/DCS/PCS power amplifierCGY2014TT
FEATURES
• Operating at 3.6 V battery supply
• Power Amplifier (PA) output power:
35 dBm in GSM band and 32.5 dBm in DCS/PCS band
• Input power: 0 dBm in GSM band and 3 dBm in
DCS/PCS band
• Wide operating temperature range from −20 to +85 °C
GENERAL DESCRIPTION
The CGY2014TT is a dual-band GSM/DCS/PCS GaAs
Monolithic Microwave Integrated Circuit (MMIC) power
amplifier. The circuit is specifically designed to operate at
3.6 V battery supply voltage.
The power amplifier requires only a 30 dB harmonic
low-pass filter to comply with the transmit spurious
specification.
• HTSSOP20 exposed die pad package.
The voltages applied on pinsVDD(drain) control the power
of the power amplifier and permit to switch it off.
APPLICATIONS
• Dual-band systems: Low Band (LB) from
880 to 915 MHz hand-held transceiversfor E-GSM and
High Band (HB) from 1710 to 1910 MHz for DCS/PCS
applications.

The CGY2014TT is designed to meet the European
Telecommunications Standards Institute (ETSI) GSM
documents, the
“ETS 300 577 specification”
, which are
defined as follows:
• ton= 570 µs
• T = 4.16 ms
• Duty cycle δ =1/8.
Multislot operation can be implemented provided that the
application circuit does not drive the IC beyond the limiting
values.
Power amplifier
The GSM and DCS/PCS power amplifiers consist of three
cascaded gain stages with an open-drain configuration.
Each drain has to be loaded externally by an adequate
reactive circuit which also has to be a DC path to the
supply.

SOLDERING
Introduction to soldering surface mount packages
Thistextgivesaverybriefinsighttoa 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 can still be used for
certainsurfacemountICs,butitisnotsuitableforfinepitch
SMDs. In these situations reflow soldering is
recommended.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
totheprinted-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
convection or convection/infrared 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 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemountdevices(SMDs)orprinted-circuitboards
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.
• Forpackageswithleadsonfoursides,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
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
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.
