The invention discloses an aluminum nitride ceramic substrate 100W loading plate with the impedance of 50 ohm. The aluminum nitride ceramic substrate 100W loading plate comprises a 5.7*8.9*1.0mm aluminum nitride substrate, wherein a back conducting layer is printed on the back side of the aluminum nitride substrate; a resistor and a lead are printed on the front side of the aluminum nitride substrate; the lead is connected with the resistor to form a load circuit; the ground terminal of the load circuit is electrically connected with the back conducting layer; and a glass protecting film is printed on the resistor. The aluminum nitride ceramic substrate 100W loading plate with the impedance of 50 ohm of the structure has favorable VSWR (Voltage Standing Wave Ratio) performance; the power of the high-power aluminum nitride ceramic substrate loading plate on the 5.7*8.9*1.0mm aluminum nitride substrate reaches 100W; and meanwhile, the capacity of the high-power aluminum nitride ceramic substrate 100W loading plate is ensured to reach 3G, the power of the aluminum nitride ceramic substrate loading plate with the size is improved to be 100W on the premise of excellent performance, the service range of the aluminum nitride ceramic substrate with the size is wider and the aluminum nitride ceramic substrate with the size can be better matched with equipment.
Description
technical field [0001] The invention relates to a loading sheet of an aluminum nitride ceramic substrate, in particular to a 100-watt loading sheet of an aluminum nitride ceramic substrate with an impedance of 50Ω. Background technique [0002] The aluminum nitride ceramic substrate load plate is mainly used in the communication base station to absorb the reverse input power of the communication components. If it cannot withstand the required power, the load will burn out, which may cause the entire device to burn out. At present, domestic aluminum nitride ceramic substrate load sheets are all used in the field of civil communication, and the frequency requirement of civil communication is 3G and within 3G. For the load chip, to be able to meet the requirements of the application, one needs to be able to meet the power requirements, and the other is the characteristics of the product, that is, the VSWR (standing wave ratio) should be as small as possible. The current market ...
