## Overview

The Oumefar Broadband Pre-tensioning T-Piece Bias Tee Inductance Amplifier Module offers ultra broadband operation from 10MHz to 6GHz with less than 1.2dB insertion loss. It features DC isolation up to 150V and supports currents below 0.5A, making it ideal for optical modulation drives, broadband amplification, and advanced test and measurement applications.

## Description

desertcart.com: Oumefar Broadband Pre-tensioning T-Piece Bias Tee Inductance Amplifier Module Coaxial Bias Tee for Optical Modulation Drive : Industrial & Scientific

Review: Performance is good - I recently used this Bias-T from and I’m quite happy with the performance. It covers a large frequency range, and even at about 500 MHz the insertion loss is only around –2 dB. That’s very good considering the bandwidth. It handled the DC feed and RF path cleanly and gave me reliable behaviour. The build quality is acceptable and the price was a great deal for what it offers.
Review: Worked reliably - I used this bias-T to power up a pre-amplifier for a VHF transmitter test. The device stayed cool and worked like a charm.

### ⭐⭐⭐⭐⭐ Adds remote power without signal attenuation...
*by R***D on August 9, 2022*

I am using this to send power upstream to a broadband preamp at my antenna location. Before inserting the preamp, I put this unit between the antenna and receiver and found attenuation to be minimal. Enclosure provides excellent shielding. Soldering and insulating power supply lead is required but not difficult. It's been powering my preamp 100 feet away for over a week now with no difficulty. I'm a happy customer!
