Embedded Micro Miniature Active GNSS Module

Parsec Technologies Inc. / Antenna Modules / PTA/PT Passive or Active Antenna Modules

Product Description

Parsec’s PTA1.5M is the world’s smallest GNSS/GPS L1 high radiated efficiency active antenna at 9 x 15 mm (L x W). The PTA1.5M integrates easily with the Telit Jupiter SE880 GPS 3D-SIP with only one direct connection required and is compatible with any GNSS receiver operating from 1560 to 1610 MHz. Ideal for embedded LBS receivers requiring good user experience that operate with obstructed view of orbiting satellites. The PTA1.5M improves GNSS receiver sensitivity to offset high path loss, improves immunity to receiver descending caused by close proximity radio transceivers, and mitigates the effects of interference from radio mixing products. Patents pending.

Key Benefits

  • micro miniature size (9 x 15 mm, LxW)
  • 50-MHz Bandwidth: covers GNSS systems from 1560-1610 MHz
  • highest radiated efficiency, ɳ, in class (>60% over rated 50-MHz BW)
  • antenna gain, Ga = 1.4 dBi @ Fc = 1575.42 MHz
  • outperforms ceramic patch antennas >4X as large in area
  • highest IP3 (linearity) in class (+18 dBm @5mA Icc)
  • improves GNSS 3D-SIP/SoC receiver SFDR >25-dB
  • ultra-low power consumption (7mW: +1.4Vdc * 5mA)
  • ultra-low noise (1.0 dB NF, typical); SAW filter OPTIONAL
  • high flat gain (15-dB delivered to the GNSS/GPS receiver)
  • Any VoltageSM operation from +1.4 to +6.0 Vdc
  • no matching required (50 ohm RF Out)

Family Concept

The PTA1.5M is one of Parsec’s PTA/PT Family of active antenna and GNSS front end modules (FEMs). Add any PTA/PT active antenna or FEM to your GNSS/GPS 3D-SIP or SoC to improve the receiver’s spurious free dynamic range (SFDR) up to 30-dB. Integrating the PTA1.5M to your Telit Jupiter SE880 3D-SIP GPS receiver is as easy as RF gets and is your lowest cost method to mitigate the effects of unintentional interference and receiver desensing while guaranteeing a good user experience.

The PTA1.5M high linearity active antenna is ideal for enhancing location based service (LBS) receivers to improve immunity to unintentional interference and receiver desensing caused by close proximity radio transmissions. The PTA1.5M’s singular set of characteristics are essential to make LBS devices that operate in applications with high path loss, obstructed view to orbiting satellites, and/or high receiver site signal attenuation work with good user experience. Employ Parsec’s PTA/PT Family of active antennas and front-end-modules (FEMs) in any commercial-class embedded LBS receiver; in particular high multipath indoor, urban canyon, wearables, container-based asset tracking, under vehicle dash OBD, and ultra-miniature module (e.g., M2/NGFF) applications.

PTA/PT Passive or Active Antenna Modules


GNSS (Global Navigation Satellite System) is a satellite system that is used to pinpoint the geographic location of a user’s receiver anywhere in the world. Two GNSS systems are currently in operation: the United States’ Global Positioning System (GPS) and the Russian Federation’s Global Orbiting Navigation Satellite System (GLONASS). A third, Europe’s Galileo, is slated to reach full operational capacity in 2008. Each of the GNSS systems employs a constellation of orbiting satellites working in conjunction with a network of ground stations.

Depending on the particular technologies used, GNSS precision varies. For example, the United States Department of Defense originally used an intentional degradation (known as “Selective Availability,” or “SA”) of GPS signals to prevent potential military adversaries from using the positioning data. Because of SA, GPS accuracy was limited to a 100-meter range for civilian users, although military equipment enabled accuracy to within a single meter. In May 2000, a presidential order mandated that SA be discontinued. Without SA, all GPS receivers are potentially accurate to within 15 meters. When available, Galileo will provide position accuracy to within one meter.
