OM7814: GPS low-noise amplifier evaluation board using BGU7004
The BGU7004 GPS front-end evaluation board simplifies the evaluation of the BGU7004 LNA for the GPS application. Two Surface Acoustic Wave filters have been added to facilitate the evaluation of the complete GPS front-end. The board is fully assembled with the BGU7004, two identical SAW filters, the input series inductor and a decoupling capacitor. The board is supplied with two SMA connectors for input and output connection to RF test equipment. The BGU7004 can operate from a 1.5 V to 2.85 V single supply and consumes about 4.7 mA.
