1. Introduction

NXP Semiconductors' BGU7004 is an AEC-Q100 qualified low-noise amplifier for GPS
receiver applications in a plastic, leadless 6 pin, extremely thin small outline SOT886
package. It has a gain of 16.5 dB gain and a noise figure of 0.8 dB, 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 110 GHz f
process. The BGU7004 only requires two external components, one series inductor for
input matching and one decoupling capacitor. The BGU7004 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 BGU7004 is ideal for use as GPS LNA in handsets, PDA's and PND's.
The GPS LNA evaluation board (EVB) see
performance of the BGU7004 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.
