400 – 500 MHz High Power 1200 W Bias Tee – Remote Powering Outdoor
What’s a Bias Tee?
A “Bias-Tee” also known as a “DC Inserter” is a simple way to feed DC power through coaxial cable to the remote device such as pre-amplifier and/or or transmit / receive relays via the coaxial cable.
Like EME2-432, EME3-432 or Preamplifiers.
Main task is to inject DC current into, or extract DC current from coaxial cable, leaving the RF signal undisturbed.
Bias tee is passive RF circuits consisting of a capacitors and inductor. Act as diplexer by combining DC and RF signals onto a common port RF+DC.
Antennas-Amplifiers “70cm Bias Tee” has impressive RF performance on whole 70 cm band 430-450MHz or full range 400-500MHz and high power handling 1200 W.
Best in-class electrical performance:
|Frequency Range:||400 – 500 MHz|
|Max Power SWR 1:1||1200 W|
|Insertion loss:||0.01 dB|
|Input Return Loss:||-35 dB|
|Isolation RF port to DC port:||80 dB|
|DC resistance from DC to RF:||0.15 Ω|
|Supply Voltage:||30 V|
|Supply Current:||1 A|
Permanent damage may occur if any of these limits are exceeded.
70 cm 1200 W Ultimate High Power Bias-Tee 430-450 MHz Measured extreme high DC-RF isolation 80 dB that minimizes RF signal leakage and interference with other devices.
70 cm Bias Tee 430 – 450 MHz High Power 1200 W Measured Super Low Loss Insertion Loss and excellent Return Loss
Recommended position of 70 cm outdoor Bias-Tee is at the end of the coaxial cable to pass DC power to the remote device.
Inject DC into Coaxial cable.
Extracts DC from Coaxial cable.
