NXP SiGe:C GPS LNAs
BGU700x/BGU8007
The best reception of GNSS signals
with the smallest footprint
By dynamically suppressing strong cellular and WLAN transmit signals, an industry first, these LNAs
offer the best reception of weak GPS signals. Linearity improves with a 10 dB better IP3 under -40 to
-20 dBm jamming conditions, while NF remains below 1 dB. Requiring only two external components,
they save up to 50% in PCB size and 10% in component cost, offering the smallest footprint in the market.
Key features
 Low noise figure: 0.75 dB
 System-optimized gain of 16.5 or 19 dB
 Adaptive biasing dynamically suppresses strong cellular and
WLAN transmit signals, resulting in improved linearity of
10 dB better IP3 under -40 to -20 dBm jamming conditions
and effective GPS output with jammer powers up to -15 dBm.
 AEC-Q100 qualified (BGU7004, BGU7008) for highest
reliability in harsh conditions
 Only two external components required
 Small 6-pin leadless package: 1.45 x 1.0 x 0.5 mm
Key benefits
 Maintains optimal GPS signal reception for as long as possible
 Significant PCB size savings (50%)
 Lower component cost (10%)
Applications
 Smart phones, feature phones
 Tablets
 Personal Navigation Devices (PNDs)
 Digital Still Camera (DSCs)
 Digital Video Camera (DVCs)
 RF front-end modules (used in phones)
 Complete GPS chipset modules (used in DSCs)
 Automotive applications (BGU7004/8) : toll collection,
emergency call
These SiGe:C low noise amplifiers (LNAs) improve the
reception of GPS signals, including GloNass and Galileo.
Available in extremely small 6-pin packages, they reduce
footprint, lower cost, and enhance reception in systems that
use an active or patch antenna.
GPS has become a standard feature in a very wide range of
consumer products, from personal navigation devices to digital
video cameras, watches, electric cars, and more. GPS signal
power levels are weak and below the noise floor at -155 dBm.
In many of these products, especially smart phones, strong
transmitters such as WLAN and cellular can drive the GPS LNA
into compression. When the GPS LNA is in compression, it has
lower gain which causes worse GPS reception. And when in
