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. miniaturized gps receiver for passive and active antennas a1084-a/b positioning products bench marking sensitivity fastest ttff (time to first fix) ultra-low power consumption smallest footprint antenna dual antenna support -159 dbm tracking < 35 s under cold start conditions (typical) 86 mw average in tracking mode 15 x 15 mm 2 passive and active antenna supported rf switch on a1084-a get your sample or evaluation-kit and see for yourself!
