~The TW***7/TW***9 is a very low power, compact wideband GNSS
antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS &
MSAS) frequency bands (***5 to ***6 MHz.
This antenna features a bigger patch element with *0% wider
bandwidth and a smaller foot print than most of its competitors.
The LNA has a typical current consumption of just 1.*5mA, with
constant characteristics over supply voltages from 2.5V to *6V. The
LNA is a two stage amplifier with a mid-section high rejection SAW
filter, with an optional anti-jamming pre-filter(TW***9).
The TW***7/TW***9 are amongst the lowest power devices available,
yet still provide excellent noise figure with *1dB nominal gain
(TW***7).
The TW***9 variant provides a “Brick-Wall” pre-filter to protect
against saturation by high level sub-harmonics and near L-Band
signals.
The TW***7/TW***9 are housed in a very small footprint IP*7
compliant magnetic mount enclosure.
