BGU8004 GNSS LNA EVB

2. General description

Modern smart phones have multiple radio systems, so problems like co-habitation are

quite common. A GNSS receiver implemented in a mobile phone requires the following

factors to be taken into account.

All the different transmit signals that are active in smart phones and tablets can cause

problems like intermodulation and compression.

Since the GNSS receiver needs to receive signals with an average power level of -130

dBm, sensitivity is very important. Many of the available GNSS ICs have integrated LNA

front ends. The noise performance of these integrated LNA front ends, and as a result

the system sensitivity, is not always adequate. The GNSS receiver sensitivity is a

measure for how accurate the coordinates are calculated. The GNSS signal reception

can be improved by a so called GNSS front end, which improves the sensitivity by

filtering out the unwanted jamming signals and by amplifying the wanted GNSS signal

with a low noise amplifier.

The pre-filters and post filters are needed to improve the overall linearity of the system as

well as to avoid overdriving the integrated LNA stage of the GNSS receiver.

3. BGU8004 GNSS LNA evaluation board

The BGU8004 LNA evaluation board simplifies the RF evaluation of the BGU8004 GNSS

LNA applied in a GNSS front-end, often used in mobile cell phones. The evaluation

board enables testing of the device RF performance and requires no additional support

circuitry. The board is fully assembled with the BGU8004, including the input series

inductor and decoupling capacitor. The board is supplied with two SMA connectors for

input and output connection to RF test equipment. The BGU8004 can operate from a 1.5

V to 3.1 V single supply and consumes about 3.6 mA.
