The Tallysman TW600 family of low noise choke ring amplifiers (LNA) are optimised for all GNSS bands.
As a result they can be utilised by the GPS, GLONASS, Galileo, and BeiDou satellite systems.
There are specific models covering different satellite constellations:
TW61x: covers all GNSS Signals (1164 -1300MHz + 1559-1610MHz)
TW62x: covers L1/L2, G1/G2, B1/B2, E1 + L-band (1195-1254MHz + 1525-1610MHz)
TW63x: covers L1/L2/L5, G1/G2/G3, B1/B2, E1/E5a+b (1164-1254MHz + 1559-1610MHz)
TW60x: covers all GNSS Signals + L-Band (1164-1300MHz + 1525-1610MHz)
In addition to this each model provides 35dB or 50dB gain.
Models with TW6x3 provide 35dB gain and models with TW6x5 provide 50dB gain.
All models meet the requirements of high performance GNSS receivers.
In particular the current consumption is less than 50mA and uses a 5 VDC supply.
Tallysman TW600 choke ring antenna amplifier features:
Available with 35 dB or 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
There are many benefits of using the Tallysman TW600 family of amplifiers.
Such as Upgrades choke ring antennas to receive the full GNSS band or subset thereof. Together with high gain enables extended cable runs and being easy to install.
