A RF Dummy Load is a necessity, regardless of whether you are a professional technician or an enthusiast of amateur radio. Your RF equipment will not be damaged if you have the appropriate dummy load. Dummy loads come in many different varieties on the market. You are certain to locate what you require, regardless of whether you are looking for a dry dummy load, an MFJ dummy load, or an RF Termination dummy load.
-45,46,38,39The MFJ Dry Dummy Loads 200w series of dummy loads is made to deliver 35W of continuous power for ten minutes at a maximum of Dummy load 200w for five seconds. They can be threaded through a flange or mounted on a flat flange and measure 1.3 inches by 4.75 inches by 1.5 inches. They have a built-in male connector and are cooled by air. Additionally available are the MFJ-4117, MFJ-989D, and MFJ-986 antenna tuners.
The "Differential T" Rotary-L tuning design, X-needle peak reading metering, and a maximum RF power rating of 3 kW distinguish the MFJ-989D antenna tuner. A MFJ-4117 mixer and a 300W peak dummy load are also included. Antennas fed by balanced line or coax can both be tuned by this dummy load. It has a 54" telescopic whip antenna, a gain control on the front panel, and an attenuator of 20 dB. It covers 40 MHz and up. Either the MFJ-989D on its own or as part of the MFJ-986 can be purchased.
The MFJ-1798 antenna has a 10-band vertical antenna and stands 6 meters (20 feet) tall. An 80/40/20m vertical and half-wave 80m2m versions are also available. Smaller versions of the vertical antenna, the MFJ-1792 and MFJ-1793, are also available.
Numerous applications make use of RF Termination Load. They are frequently used in DMA, UMTS, and WIFI applications because they offer resistive power terminations. RF cables can also be terminated with them. There are a variety of sizes and connector types available for these products. SMB, QMA, SMP, and N connectors are a few examples. These items can be low-tech or high-performance and are made of a variety of materials.
An antenna-replacement device is known as a dummy load. This kind of load can be made of gold-plated brass, copper, aluminum, PTFE, or aluminum oxide, among other things. A dummy load with the same impedance as the antenna it is replacing is the best. These loads should provide adequate resistance and can be made of 50 or 75 ohms. Parallel ceramic resistors made of aluminum oxide are typically used to make these devices. They can also be made of more sophisticated materials, like brass that has been nickel-plated.
A good dummy load is the RFCT 250W Square N type RF Terminations Dummy Load. It has a square heat sink and N-type male/female connector ports. Other features of this product include a low VSWR and a large power capacity.
RF sham burdens, otherwise called terminations, are utilized to test and tune radios, radar frameworks, and different gadgets that are utilized in RF applications. During testing, these devices act as an antenna and electrical load. From a small single resistor to a large array of resistors, they come in a variety of sizes and shapes. You can also choose the load's resistance with a switch on some of these devices.
A heatsink, a connector, and a resistor are the fundamental rf components of a dummy load for RF applications. Most of the time, the resistor is designed to handle the transmitting power of the device being tested. The heatsink should be big enough to handle the heat from the resistor. If not, the device may experience issues as a result of the heat generated by the resistor.
SMB, QMA, TNC, and N connectors are among the styles of RF dummy loads. These gadgets are accessible in a scope of force yields, from 0.25 Watts up to 1 Watt. You might need to think about adding more inductance for builds with higher frequencies. You can select the load's resistance with switches on some dummy loads. Water cooling of some dummy loads aids in noise reduction and RF stability.
