1. Introduction
NXP Semiconductors’ BGU8007 is a low-noise amplifier for GPS receiver applications in
a plastic, leadless 6 pin, extremely thin small outline SOT886 package. It has a current of
4.6 mA, a gain of 19 dB and a noise figure of 0.75 dB
[1]
. It has superior linearity
performance to suppress interference and noise from co-habitation cellular transmitters
while retaining sensitivity.
The LNA has been designed using NXP Semiconductors’ advanced 180 GHz f
T
SiGe:C
process. The BGU8007 only requires two external components, one series inductor for
input matching and one decoupling capacitor. The BGU8007 contains one RF stage and
internal bias that is temperature stabilized. It is also supplied with an enable function
allowing it to be controlled by a logic signal.
The BGU8007 is ideal for use as GNSS LNA in smart phones, feature phones and
Portable Navigation Devices.
The GPS LNA evaluation board (EVB), see
Fig 1
, is designed to evaluate the
performance of the BGU8007 applied as a GPS LNA. In this document, the application
diagram, board layout, bill of materials, and typical results are given, as well as some
explanations on GPS related performance parameters like out-of-band input third-order
intercept point, gain compression under jamming and noise under jamming.
