TW1010/TW1012 Embedded GPS L1 Antenna
The TW1010/TW1012 by Tallysman Wireless is low
cost, high gain, high performance, embedded GPS L1
antenna, specially designed for OEM industrial,
military, precision positioning and timing applications.
The TW1010/TW1012 features a precisely tuned
single feed ceramic patch element. It has a two stage
Low Noise Amplifier (LNA) with a mid-section SAW.
An optional tight pre-filter is available with part
number TW1012 to protect against saturation by high
level sub-harmonics and L-Band signals.
The TW1010/TW1012 covers the GPS L1 and SBAS
(WAAS /EGNOS/MSAS) frequency band (1572.5 to
1578 MHz), and it offers great circular polarized signal
reception, multipath rejection and out of band signal
rejection.
The TW1010/TW1012 has a built-in 35mm circular
ground plane that can be augmented with host system
ground surfaces. Patch Elements are susceptible to
detuning by the local environment.
Tallysman offers
