TW154 Datasheet

TW154 Regulated 0.5 to 3GHz, 3.3V Bias-Tee

The TW154 by Tallysman Wireless is a professional grade wideband Bias-Tee for injecting DC voltages onto coaxial lines. The regulated output voltage and the large output current makes this product highly suitable for many active antennas and amplifiers. It is useable up to 6GHz with higher insertion loss (see data below).

The TW154 is housed in a robust RF sealed, weatherproof (IP67) clear anodized aluminum enclosure and is available with 3 x SMA or TNC Jack connectors.

Specifications

VCC=5V, over full bandwidth, T=25 °C

Electrical
Operational Frequency 1 to 3 GHz
VSWR (50Ω) <1.3 @ 3 GHz
Insertion Loss 1 dB @ 3 GHz
Supply Current* Output current 5 mA
Supply Voltage** 3.6 to 10 VDC
Output Voltage 3.3 VDC +/- 2.5%

* The TW154 Bias-Tee is capable of safely delivering up to 450 mA.
** The output current limit should be d-rated so as to restrict the maximum power dissipated within the regulated TW154 to 2W max,
calculated as P=(Vin-3.3)*I.
