## Overview

The Ciglow Amplifier Bias Tee is a high-quality RF wideband amplifier designed for professional applications, featuring a frequency range of 25k-100MHz, DC isolation to prevent voltage leaks, and high-frequency inductance to maintain signal integrity. Ideal for HAM radio enthusiasts and fiber optic communications, this durable device is engineered for reliability and performance.

## Description

Description: Wideband amplifier feed circuit, the high frequency is affected by the parasitic capacitance parameters, and the performance drops sharply, so the feed needs to use bias tee. Some broadband amplifiers do not have a DC blocking capacitor inside, and the output needs to be powered. A bias tee is required. Bias Tee consists of ultra-wideband, near idealized, high frequency inductors and capacitors without resonance points.  Specification: Material: PCB Working Freq: 25k-100MHz Insertion-loss: <1dB Operating Voltage: DC1-50V Maximum working current: <0.6A Size: approx. 5.9 * 2.3 * 0.3cm / 2.32 * 0.91 * 0.12in Weight: 6.6g  Package list: 1 * Bias Tee

## Features

- High quality, sturdy and durable.
- It consists of high frequency inductors and capacitors with ultra-wideband, near idealized and no resonance points.
- Isolated Capacitor: Isolate DC to prevent DC voltage from leaking to subsequent circuits or test instruments.
- High frequency inductance: Isolation of AC information to prevent high frequency signals from leaking into the power system.
- Applications: Broadband amplifiers, fiber optic communications, optical modulation drivers, and other test and measurement applications.

## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Cheaply made, but functional.
  

*by R***N on Reviewed in the United States on March 3, 2023*

I built a distribution amp, so I could feed the signal from my amplified magnetic loop antenna to three different shortwave receivers without having to switch cables. Rather than using an external t-bias that requires more cables and another power supply, I mounted this board inside my distribution amp, feeding it power from the 12v supply through a 5v regulator. I unsoldered the SMA output connector and wired it directly to the amp's input. It works fine for powering the antenna's preamp and even seems to lower the noise floor when compared with the original USB powered bias supply.I've ordered a few more of these boards, seems like a handy thing to have around.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    REALLY tiny!
  

*by J***Z on Reviewed in the United States on March 20, 2023*

I was not expecting this product to be so small and to have tiny connectors. They looked like SO-239 in the pictures but they are not even close. Other than that it works fine.
