The TW605 family of low noise amplifiers (LNA) provides a high-performance amplifier upgrade for full GNSS (GPS/QZSS, GLONASS, Galileo, BeiDou) frequency choke ring antennas.
- Available with 50 dB gain
- Low current and low voltage
- Wide input voltage range: 3 to 17 Volts
- Powered via antenna coax from receiver
- 50 Ohm port impedance
- Very low noise
- RoHS and REACH compliant
- Upgrades choke ring antennas to receive the full GNSS band or subset thereof
- High gain enables extended cable runs
- Easy to install
The TW605 family of low noise amplifiers (LNA) are optimized for all GNSS bands utilized by the GPS, GLONASS, Galileo, and BeiDou satellite systems. This LNA is designed for integration into existing choke ring antennas thereby upgrading them to receive the entire GNSS band or a subset thereof.
The TW605 provides 50 dB of gain. Custom pre-filtering provides suppression of out-of-band interfering signals such as cellular LTE, Ligado, and Iridium satellite communications, while maintaining a low noise figure, high third order intercept point and small group delay.
Meeting the requirements of high performance GNSS receivers, the current consumption is less than 50mA with a 5 VDC supply.
The amplifier housing is compatible with choke ring antennas manufactured by Trimble, Allen Osborne, Ashtech, and Leica (504)
