TW1320/TW1322 Embedded GPS/GLONASS Antenna
The TW1320/TW1322 is a high performance OEM GNSS
antenna covering the GPS L1, GLONASS L1 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 1dB RHCP received power
bandwidth.
The TW1320/TW1322 has a two stage Low Noise
Amplifier (LNA) with a mid-section SAW. An optional
tight pre-filter is available with part number TW1322 to
protect against saturation by high level sub-harmonics
and L-Band signals.
The built-in 35mm 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. Tallysman offers custom tuning services
for optimized integration into OEM end-user modules.
