PAM-7Q - u-blox 7 GPS antenna module

The u-blox PAM-7Q patch antenna module delivers high sensitivity and minimal acquisition times in an industry proven form factor.

The u-blox PAM-7Q patch antenna module has the exceptional performance of the u-blox 7 GNSS engine and delivers high sensitivity and minimal acquisition times in an industry proven form factor. Incorporating the PAM-7Q into customer designs is simple and straightforward, thanks to the embedded antenna, low power consumption, simple interface, and sophisticated interference suppression that ensures maximum performance even in GPS hostile environments.

The 18 x 18 mm patch antenna of PAM-7Q provides RHCP polarization, which is not achievable with smaller patch antenna elements. The simple design and easy interfacing keeps installation costs to a minimum.

Key Features:

  • Embedded GPS antenna
  • Excellent antenna performance
  • Low power consumption
  • Form-factor compatible with UP501
  • Easy integration into design
