APPLICATION INFORMATION
In Fig.6 the MMIC is used as a driver to the power amplifier
as part of a transmitter circuit. Good linear performance
and matched input and output offer quick design solutions
in such applications.
Figure 2 shows a typical application circuit for the
BGA2771 MMIC. The device is internally matched to 50 ,
and therefore does not need any external matching. The
value of the input and output DC blocking capacitors C2
and C3 should be not more than 100 pF for applications
above 100 MHz. However, when the device is operated
below 100 MHz, the capacitor value should be increased.
DC-block
handbook, halfpage
The nominal value of the RF choke L1 is 100 nH. At
frequencies below 100 MHz this value should be
increased to 220 nH. At frequencies above 1 GHz a much
lower value must be used (e.g. 10 nH) to improve return
losses. For optimal results, a good quality chip inductor
such as the TDK MLG 1608 (0603), or a wire-wound SMD
type should be chosen.

Fig.3 Simple cascade circuit.
Both the RF choke L1 and the 22 nF supply decoupling
capacitor C1 should be located as closely as possible to
the MMIC.
Separate paths must be used for the ground planes of the
ground pins GND1 and GND2, and these paths must be as
short as possible. When using vias, use multiple vias per
pin in order to limit ground path inductance.

agreement be valid in which the NXP Semiconductors
product is deemed to offer functions and qualities beyond
those described in the Product data sheet.
Suitability for use  NXP Semiconductors products are
not designed, authorized or warranted to be suitable for
use in life support, life-critical or safety-critical systems or
equipment, nor in applications where failure or malfunction
of an NXP Semiconductors product can reasonably be
expected to result in personal injury, death or severe
property or environmental damage. NXP Semiconductors
accepts no liability for inclusion and/or use of NXP
Semiconductors products in such equipment or
applications and therefore such inclusion and/or use is at
the customer’s own risk.

any of these products are for illustrative purposes only.
NXP Semiconductors makes no representation or
warranty that such applications will be suitable for the
specified use without further testing or modification.
In no event shall NXP Semiconductors be liable for any
indirect, incidental, punitive, special or consequential
damages (including - without limitation - lost profits, lost
savings, business interruption, costs related to the
removal or replacement of any products or rework
charges) whether or not such damages are based on tort
(including negligence), warranty, breach of contract or any
other legal theory.
Customers are responsible for the design and operation of
their applications and products using NXP
Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or
customer product design. It is customer’s sole
responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the
customer’s applications and products planned, as well as
for the planned application and use of customer’s third
party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks
associated with their applications and products.
Notwithstanding any damages that customer might incur
for any reason whatsoever, NXP Semiconductors’
aggregate and cumulative liability towards customer for
the products described herein shall be limited in
accordance with the Terms and conditions of commercial
sale of NXP Semiconductors.

Export control  This document as well as the item(s)
described herein may be subject to export control
regulations. Export might require a prior authorization from
national authorities.
NXP Semiconductors does not accept any liability related
to any default, damage, costs or problem which is based
on any weakness or default in the customer’s applications
or products, or the application or use by customer’s third
party customer(s). Customer is responsible for doing all
necessary testing for the customer’s applications and
products using NXP Semiconductors products in order to
avoid a default of the applications and the products or of
the application or use by customer’s third party
customer(s). NXP does not accept any liability in this
respect.
Quick reference data  The Quick reference data is an
extract of the product data given in the Limiting values and
Characteristics sections of this document, and as such is
not complete, exhaustive or legally binding.
Non-automotive qualified products  Unless this data
sheet expressly states that this specific NXP
Semiconductors product is automotive qualified, the
product is not suitable for automotive use. It is neither
qualified nor tested in accordance with automotive testing
or application requirements. NXP Semiconductors accepts
no liability for inclusion and/or use of non-automotive
qualified products in automotive equipment or
applications.
Limiting values  Stress above one or more limiting
values (as defined in the Absolute Maximum Ratings
System of IEC 60134) will cause permanent damage to
the device. Limiting values are stress ratings only and
(proper) operation of the device at these or any other
conditions above those given in the Recommended
operating conditions section (if present) or the
Characteristics sections of this document is not warranted.
Constant or repeated exposure to limiting values will
permanently and irreversibly affect the quality and
reliability of the device.
In the event that customer uses the product for design-in
and use in automotive applications to automotive
specifications and standards, customer (a) shall use the
product without NXP Semiconductors’ warranty of the
product for such automotive applications, use and
specifications, and (b) whenever customer uses the
product for automotive applications beyond NXP
Semiconductors’ specifications such use shall be solely at
customer’s own risk, and (c) customer fully indemnifies
NXP Semiconductors for any liability, damages or failed
product claims resulting from customer design and use of
the product for automotive applications beyond NXP
Semiconductors’ standard warranty and NXP
Semiconductors’ product specifications.
