EMC-RFLABS is an internationally recognized leader in the development and manufacture of thin and thick film RF microwave resistor components, signal distribution products, and cable assemblies. Its products are widely used in telecommunications, military, broadcast equipment, space, aerospace, medical equipment and test and measurement markets. A full range of high-power RF load series is available, including SMD, leaded, coaxial flanged, SMA, with wire flange, surface mount, gold wire and style. These loads have an optimized very low VSWR and can be used in broadband applications. Some devices have a power capacity of 1 kW and a maximum frequency of 26.5 GHz. Different substrates can also be provided, such as aluminum, yttria, alumina and diamond materials. Easy to solder and supports a variety of mounting methods.
Among them, the surface mount type load resistor can be used as three different types of loads, whether in the face of RF or DC applications such as: bias voltage drop or heater. Type A loads have a complete metallized back that can be connected directly to a heat sink or a device for heating. Type B loads are omnidirectional dispensers for low power SMT applications. The Type C load has a separate grounding area that allows it to be mounted as a resistor or load. Because this type provides a larger area and increases heat dissipation area, it is an ideal choice for high power SMT applications.
The SMT series of surface mount loads from EMC-RFLABS from Shiqiang suppliers include various surface mount loads with power capacities up to 240 W and frequencies up to 4 GHz. This series of loads can improve the heat dissipation of the device by increasing the ground contact area with EMC-RFLABS' unique asymmetric patented technology. There is no need to use bolts to fix heat, which reduces system cost. The SMT252503ALN2F is one of the surface mount load resistors specifically designed for direct mounting on printed circuit boards and thick film technology. The rated power and impedance are 150 W, 50 Ω, and the voltage wave ratio is as low as: 1.13:1 (Max, DC 2.7 GHz) and 1.20:1 (MAX, 2.7 – 4.0 GHz). Moreover, the metallized edges on both sides of the surface-mounting load form a soldering strip, which can enhance the adhesion, is easy to inspect, and increases the heat dissipation area. It has an operating temperature range of -55 ° C to + 150 ° C and can be used in alumina, aluminum nitride or tantalum oxide. Tape and reel packaging is optional and suitable for automated assembly. It can be applied to market areas such as mobile networks, broadcasting, high power amplifiers, instruments, optical isolators, military, satellite communications.
