The surface thin-filmfilm filter has the advantages of wide parameter range (4GHz--45GHz), small size, high line accuracy, good temperature characteristics, high integration, easy welding, light weight, good performance, high stability, good out-of-band suppression, low insertion loss, wide temperature range, 50Ω coplanar waveguide output, gold wire bonding, and multi-chip integrated module applications.
一、Characteristics
Because the yield of the thin-film filter is greatly affected by the machining error and material parameter deviation, the coupling structure between the resonators and the resonators and the input and output ports in the thin-film filter is machined together with the film filter as a whole. After the surface thin-film filter has been made, it cannot be adjusted again alone.
Thin-film circuit has the advantages of wide parameter range (4GHz--45GHz), small size, high line accuracy, good temperature characteristics, high integration, easy welding, light weight, good performance, high stability, good out-of-band suppression, low insertion loss, wide temperature range, 50Ω coplanar waveguide output, gold wire bonding, suitable for multi-chip integrated module applications, etc. This is also the feature of the surface-mounted thin-film filter made of thin-film circuit.

三、Application & attention
The Surface mount thin-film filters are widely used in aerospace, aviation, navigation, radar, electronic countermeasures, remote sensing, telemetry, navigation, civil aviation, airport tower, naval ships, microwave communications, subway communications, public security fire protection, mobile communications, satellite communications, scientific research, medical equipment, deep sea detection, high-definition image transmission, radio and television and other military and civilian microelectronics communication equipment. When in use, it is necessary to pay attention to the grounding end is well grounded, otherwise it will affect out-of-band suppression and flatness indicators, and the welding temperature cannot be too high and the time cannot be too long. The recommended temperature is recommended. Products should be stored in the ambient temperature of -10℃~40℃, relative humidity is not more than 80%, the surrounding environment is not acidic, alkaline and other harmful gases in the warehouse. Do not soak when cleaning, it is recommended to wipe with alcohol.
As a manufacturer of microwave electronic components, can accept custom to provide 3-13 order, 2GHz- 40GHz, 3dB bandwidth from 5% to 60%, coplanar waveguide input and output thin-film filter, because this product is a strong customization of the product, the user needs to put forward a clear parameter description, the device has been completed, can not be adjusted again alone. For parameters beyond the physical limits of the material, the best indicators can be achieved through mutual consultation.
