  • Great out of band signal rejection
  • Compact form factor
  • RoHS compliant

Details

Ideal for industrial, agricultural and all challenging OEM applications, the TW2408 provides truly circular response over its entire bandwidth thereby producing superior multi-path signal rejection.

The TW2408 features a dual-feed, wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage. This configuration provides excellent axial ratio that is constant across the full frequency band.

The TW2408 also includes an LNA pre-filter, providing enhanced protection against high level sub-harmonic signals like LTE and near frequency signals such as WiFi.

Tallysman offers custom tuning services to optimize the performance of the TW2408 for any OEM installation environment.
