Miniaturized GPS receiver for passive and active antennas. Many GPS applications, such as portable devices or telematics units, require a built-in antenna. However, an external antenna connector is often desired for GPS performance or reliability reasons. This is what the new A1084-A GPS receiver supports with its second antenna pin and on board antenna switch, whilst the A1084-B supports both passive and active antennas on a single antenna pin. This very compact SiRFStar III based GPS receiver comes completely shielded with a lid and with benchmark-setting GPS performance on a very small footprint.
