Thermal paste RF amplifiers

描述

New high power RF transistors pack an amazing amount of power into very small footprint. This requires very good thermal transfer to the heatsink. Best possible cooling for RF power transistors and PCB laminate in planar design pallets are critical for long life and best electrical performance for RF Power amplifiers. The best possible cooling is obtained by soldering the transistor directly to the copper base. Unfortunately this is not so easy and such transistors are hard to replace. They can even be damaged by over-heating in this way. Most companies use thermal paste of some kind. It works but it is not ideal. 

We are providing you all solutions, thermal transfer paste and also special thermal transfer pads for RF power transistors (put them between heatsink and transistors).

ASMX thermal paste
The thermal paste is the simplest solution and also the one most often used for RF power transistors. Do not apply a thick layer, keep it thin and even.
– Works with any type of heatsink metal
– Improves thermal transfer
– 射頻功率晶體管的壽命更長
– 改進的 P1dB 性能
– 改進的 IMD3 性能
– 4g or 45g plastic syringe

Metal pads for RF transistors with cleaning set
Special soft metal pads with low melting temperature that are placed between substrate and transistor.  Superior thermal conductivity with easy application which consists of 100% from a high thermal conductivity alloy and is absolutely non-toxic. At power-up as transistor warms up the metal might melt to fill the space between the substrate and transistor optimally – there remains no solid residues – it is also suitable for application to aluminum surfaces and other metals
– 3 pads 40x40mm size, sufficient for about 6 transistors, cut to size
– Cleaning set included, ensure good clean surface
– Not as easy to work with
