Passive GPS/GNSS Antennas
July 15, 2015

Parsec’s PTA1.5M are a family of GNSS/GPS L1 high radiated efficiency active antennas. The PTA1.5M family integrates easily with industry leading GNSS/GPS 3D-SIP and system on chip (SoC) receivers with only a single direct connection typically 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 within 5 to 7 mm of the human body, indoors in the presence of mulipath, and in applications with obstructed view of orbiting satellites. Patents pending.

Key Benefits

  • 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-9 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.
