2019年11月17日 · Homebrew construction of 2 and 4 port splitters/combiners for the LF-MF-HF (30 kHz-30 MHz) frequency range. This is a follow-up of a previous article, "Characterizing the Mini-Circuits ZFSC-4-3, ZFDC-20-3, ZFSC-4-1-BNC+ and ZFSC-2-1+ well below their designed frequency range" - link.

The solution was to build a simple antenna splitter which allows the 2 radio receivers to connect to the single coaxial antenna feed line while preserving the correct impedance at all connection points. This project is based upon the splitter presented in EMRFD labeled Figure 3.81.

2019年3月2日 · I was looking for a simple project to split a RX antenna into two receivers, my Wellbrook loop feeds my Kiwi SDR and also my HF radio. The Wellbrook loop is very capable at LF and MF frequencies, and so makes a great alternative for RX on 472 KHz and even NBD reception should my local noise allow.

Antenna splitters that offer four output ports contain three "building blocks" arranged in a cascade fashion, where the first unit splits the signal into two halves, which are then fed into a second rank of two splitters; those second rank splitters divide the half signals into halves again, creating four identical signals of further diminished ...

Abstract: Developing efficient power-splitting device for multichannel distributed low-frequency (LF) mechanical antenna (MA) communication system is challenging since conventional LF power-splitting technologies rely on lumped resistive elements with unsatisfied efficiency and poor electrical isolation. In view of this, a magnetoelectric (ME ...

A "magic T" splitter or combiner is very easy to build, and that's all Mini-Circuits or a CATV manufacturer will sell you. I often just use a chunk of old PC board as a "chassis". 1. Wind a bifilar winding on a ferrite core, 73 to 77 mix will work fine.

2019年5月19日 · Dual-core power splitters. Here are some classic power splitter/combiner designs using two separate ferrite cores The typical design works quite well over the entire HF band and beyond and it can be further optimized to improve its performances at the lower end. The splitter basic schematic:

Combiners and splitters (CS) are very useful devices in receive and transmit applications where signals need to be combined (from several antennas for example)or signals need to be split (into two amplifiers for example). They can provide equal voltages, equal current, or equal power to matched or unmatched loads.

2019年11月29日 · This is a simple antenna splitter I built to connect an antenna to two distinct receivers. I found the schematic diagram in the excellent article by John Bryant and Bill Bowers on dxing.info . Splitters are expensive if you buy them, but they are very simple to build.

2023年5月15日 · A compact, passive magnetoelectric (ME) power splitter, with a ferrite/piezoelectric transformer bilayer composite with a coil wound around it, as well as a structure-constructing strategy, was presented and developed in this research.
