Operating from 25kHz to 100MHz with less than 1dB insertion loss, it isolates DC voltage (1-50V) to protect sensitive circuits while maintaining signal integrity. Its resonance-free design and compact PCB build make it an essential tool for broadband amplifiers, fiber optic communications, and precision test environments. ## 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 Review: It has no amplifier , it’s just a T bios - This is a bios T. It does not have an amplifier, it reduce the signal around 1dB , its job is to supply voltage to an active antenna , be warned what you put in is what comes out. Review: Good performance, annoying power connection. - Good performance from about 250kHz up, allowing it be used on HF and shortwave, unlike ones that use much smaller inductors. The power solder points on it are a bit odd. The ground has a through hole, the power doesn't. Most of the other tees I have got allow for a header or screw terminals, which is nicer. ## Features - High quality, sturdy and - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Q3QRW2F | | Best Sellers Rank | 83,237 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 395 in Hi-Fi Amplifiers | | Brand | Garsent | | Country Of Origin | China | | Customer Reviews | 3.5 out of 5 stars 9 Reviews | | Item Dimensions | 5.9 x 2.3 x 0.3 centimetres | | Item Weight | 9 g | | Item dimensions L x W x H | 5.9 x 2.3 x 0.3 centimetres | | Manufacturer | Garsent | | Manufacturer Part Number | aiqo8vd256 | | Material | PCB | | Maximum Supply Voltage | 50 Volts | | Maximum supply voltage | 50 Volts | | Minimum Supply Voltage | 1 Volts | | Minimum supply voltage | 1 Volts | | Model Number | aiqo8vd256 | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Number of Channels | 1 | | Number of Items | 1 | | Number of Packs | 1 | | Package Type Name | Single Unit | | Supply Current | 0.6 Milliamps | | UPC | 703633234919 | | Unit Count | 1.0 count | | Voltage | 50 Volts | ## Product Details - **Item dimensions L x W x H:** 5.9 x 2.3 x 0.3 centimetres - **Manufacturer:** Garsent - **Maximum supply voltage:** 50 Volts - **Minimum supply voltage:** 1 Volts - **Voltage:** 50 Volts ## Images ![– Garsent Amplifier Bias Tee, 25k -100MHz RF Wideband Amplifier Coaxial Feed Bias Tee for HAM Radio RTL SDR LNA. - Image 1](https://m.media-amazon.com/images/I/6113s0CK-3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ It has no amplifier , it’s just a T bios *by B***2 on 30 June 2025* This is a bios T.
