RF attenuator Co-TCA series

variable

US Utility patent No. US7,362,196 B2 ETC EU, China, Taiwan，Korea patented - ● Frequency range: DC to 3GHz, DC to 6GHz,DC to 12.4GHz，DC to 18GHz ● Power rating: 100mW,200mW,2W ● Impedance: 50Ω or 75Ω ● Operating temperature: -55℃ to +150℃ ● Excellent acteristics of attenuation compensating: wide attenuation variable range and low VSWR of temperature from -55℃to +150℃, especially at the frequency of 1GHz, 3GHz and 6GHz. ●10 attenuations from 1dB to 10dB and 7 variation slope acteristics from N3 to N9. Besides, custom services are available for p/n with larger slopes like N10 or N11. ● Adopting 100% laser trimming, high attenuation accuracy. ● High reliability. Adopting advanced thick film technology through firing at the high temperature of 850 ℃. ● Zero Distortion, and no phase changes and time delay caused by temperature variation. ● Temperature compensation and RF isolation, which are more suitable for multi-stage power amplifiers. ● No extra IP3 exists and suitable for linear power amplifier. ● Low cost and small size. It can be easily designed in RFpower amplifier to replace AGC loop circuit, which is easy for the regeneration of RF circuit ●SMA and N type available. The connectorized attenuator is easy for connection and good for improvement of system temperature acteristics. ● Power Amplifier ● Low Noise Amplifier ● Gain Blocks ● Optical Transceiver Module ● MMIC Amplifiers ● WLAN (2.4GHz or 5.8GHz) ● WiMAX ● UWB ● Mixers ● Power Dividers ● Satellite Communication ● Directional Couplers ● Broadcast (TV & Radio) ● Radar ● Substrate: Alumina (Al2O3) ● Resistive material: Thick film ● Terminal material:
