TW1322 Embedded Single Band GNSS Antenna

The TW1322 is a high performance OEM GNSS antenna covering the GPS-L1, GLONASS-G1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It features a patch element with 40% wider bandwidth than previously available in this format. Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1 dB RHCP received power bandwidth.

The TW1322 has a two stage low-noise amplifier (LNA) with a mid-section SAW. TA tight pre-filter on the TW1322 to protect against saturation by high-level sub-harmonics and L-Band signals. The built-in 35 mm circular ground plane should ideally be augmented with a local system ground plane or reflecting surface (DC connection not required).

OEM antennas are easily detuned by the local environment. Calian offers custom tuning services for optimized integration into OEM end-user modules.
