2. General description
NXP Semiconductors’ BGU8007 low noise amplifier is dedicated for the GNSS frequency
band (GPS, GLONASS and Galileo positioning systems). The integrated biasing circuit is
temperature stabilized, which maintains a constant current over temperature. It also
enables the superior linearity performance of the BGU8007. It is also supplied with an
enable function that allows it to be controlled with a logic signal. In disabled mode it
consumes less than 1 µA.
The output of the BGU8007 is internally matched for 1575.42 MHz whereas only one
series inductor at the input is needed to achieve the best RF performance. Both the input
and output are AC coupled via an integrated capacitor.
Only two external components are required to build a GPS LNA with the following
advantages:
Low noise;
High gain;
High linearity under jamming;
Very low package height 0.5mm;
Low current consumption;
Short power settling time;
The data sheet of the BGU8007 is available, and it is called “SiGe:C Low Noise Amplifier
MMIC for GPS, GLONASS and Galileo”
3. Application Board
The BGU8007 GPS LNA evaluation board simplifies the evaluation of the BGU8007 GPS
LNA for the GNSS applications. The evaluation board enables testing of the device
performance and requires no additional support circuitry. The board is fully assembled
with the BGU8007, including the input series inductor as well as a decoupling capacitor
to optimize the performance. The board is supplied with two SMA connectors for input
and output connection to RF test equipment. The BGU8007 can operate from a 1.5 V to
2.2 V single supply and consumes about 4.6mA.
