TW1027 Embedded Single Band GNSS Antenna

The TW4027 is a very low power, compact GNSS antenna covering the GPS/QZSS L1, as well as SBAS (WAAS, EGNOS & MSAS).

The TW1027 is a very low power, compact GNSS antenna covering the GPS-L1, frequency band. This antenna features an LNA with a nominal current consumption of just 1.8 mA, with constant performance from 2.5V to 16V supply voltage, and includes protection against close proximity L-Band transmitting antennas such as Iridium® and Globalstar™.

The TW1027 has amongst the lowest power consumption available, yet still provides 24 dB nominal gain and an excellent noise figure. The TW1027 patch has 40% wider bandwidth for better axial ratio and has 15 kV ESD circuit protection. The LNA has a +/- 10 MHz bandwidth that covers the full GPS-L1 signal plus the SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz).

The TW1027 is available with a variety of connectors and custom cable lengths.

It is highly recommended to take advantage of Calian's custom tuning service to ensure optimal performance of this antenna in your housing and with your ground plane.
