GENERAL DESCRIPTION
UAA2077BM contains both a receiver front-end and a high
frequency transmit mixer intended to be used in mobile
telephones. Designed in an advanced BiCMOS process it
combines high performance with low power consumption
and a high degree of integration, thus reducing external
component costs and total front-end size.
The main advantage of the UAA2077BM is its ability to
provide over 25 dB of image rejection. Consequently, the
image filter between the LNA and the mixer is suppressed.
Image rejection is achieved in the internal architecture by
two RF mixers in quadrature and two all-pass filters in
I and Q IF channels that phase shift the IF by 45° and 135°
respectively. The two phase shifted IFs are recombined
and buffered to furnish the IF output signal.
For instance, signals presented at the RF input at the
LO + IF frequency are rejected through this signal
processing while signals at the LO − IF frequency can form
the IF signal. An internal switch enables the upper or lower
image frequency to be rejected.
The receiver section consists of a low-noise amplifier that
drives a quadrature mixer pair. The IF amplifier has
on-chip 45° and 135° phase shifting and a combining
network for image rejection. The IF driver has differential
open-collector type outputs.
The LO part consists of an internal all-pass type phase
shifter to provide quadrature LO signals to the receive
mixers. The centre frequency of the phase shifter is
adjustable for maximum image rejection in a given band.
The all-pass filters outputs are buffered before being fed to
the receive mixers.
The transmit section consists of a low-noise amplifier and
a down-conversion mixer. In the transmit mode an internal
LO buffer is used to drive the transmit IF down-conversion
mixer.
All RF and IF inputs or outputs are balanced.
Pins RXON, TXON and SXON enable a selection to be
made of whether to reject the upper or lower image
frequency and control of the different power-down modes.
Special care has been taken for fast power-up switching.

FUNCTIONAL DESCRIPTION
Receive section
The circuit contains a low-noise amplifier followed by two
high dynamic range mixers. These mixers are of the
Gilbert-cell type, the whole internal architecture is fully
differential.
The local oscillator, shifted in phase to 45° and 135°,
mixes the amplified RF to create I and Q channels.
The two I and Q channels are buffered, phase shifted by
45° and 135° respectively, amplified and recombined
internally to realize the image rejection.
Balanced signal interfaces are used for minimizing
crosstalk due to package parasitics.

MIXER
IF
amplifier
The IF output is differential and of the open-collector type.
Typical application will load the output with a differential
1kΩ load; for example, a 1 kΩ resistor load at each IF
output, plus a differential 2 kΩ load consisting of the input
impedance of the IF filter or the input impedance of the
matching network for the IF filter. The power gain refers to
the available power on this 2 kΩ load. The path to V
CC
for
the DC current should be achieved via tuning inductors.
The output voltage is limited to VCC+3Vbe or 3 diode
forward voltage drops.
Fast switching, ON/OFF, of the receive section is
controlled by the hardware input RXON.

Local oscillator section
The local oscillator (LO) input directly drives the two
internal all-pass networks to provide quadrature LO to the
receive mixers.
The centre frequency of the receive band is adjustable by
the voltage on pin V
connecting a resistor between V
. This should be achieved by
QUADLO
and VCC. Over
QUADLO
25 dB of image rejection can be obtained by an optimum
resistor value.
A synthesizer-ON mode (SX mode) is used to power-up all
LO input buffers, thus minimizing the pulling effect on the
external VCO when entering the receive or transmit mode.
This mode is active when SXON = 1.

Transmit mixer
This mixer is used for down-conversion to the transmit IF.
Its inputs are coupled to the transmit RF which is
down-converted to a modulated transmit IF frequency,
phase-locked with the baseband modulation.
The IF outputs are high-impedance (open-collector type).
Typical application will load the output with a differential
500 Ω load; for example, a 500 Ω resistor load, connected
to VCCfor DC path, at each TX output, plus a differential
1kΩ consisting of the input impedance of the matching
network for the following TX part. The mixer can also be
used for frequency up-conversion.
Fast switching ON/OFF, of the transmit section is
controlled by the hardware input TXON.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
“IC Package Databook”
Reflow soldering
Reflow soldering techniques are suitable for all SSOP
packages.
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 techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
Wave soldering
Wave soldering isnot recommended for SSOP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
(order code 9398 652 90011).
If wave soldering cannot be avoided, the following
conditions must be observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
• The longitudinal axis of the package footprint must
be parallel to the solder flow and must incorporate
solder thieves at the downstream end.
Even with these conditions, only consider wave
soldering SSOP packages that have a body width of
4.4 mm, that is SSOP16 (SOT369-1) or
SSOP20 (SOT266-1).
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.
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. 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.
Repairing soldered joints
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) 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.
