Feature:1. PCB material is used to ensure good passing performance of large and small currents.2. Each individual control circuit can be controlled by hand and program, and the large heat dissipation area can better maintain long-term operation.3. ISM, MMDS, WLAN, WiMAX, TTL, CMOS compatible control, 7V maximum supply voltage, 27dBm maximum input power.4. HMC470 RF attenuator module uses high quality electronic components, which are stable and reliable.5. Digital RF attenuator module cannot be used under overload, overvoltage, and overcurrent conditions.Specification:Item Type: Digital RF Attenuator ModuleMaterial: PCBModel: HMC470Supply Voltage: Maximum Voltage 7VMaximum Input Power: 27dBmControl Voltage Range: (V1-V5): -1V~Vdd +1VTest Parameters: (Vector Scanning Power: 0dBm)Insertion Loss: No Attenuation (V1-V5 = 11111)Step Error: 0.3 DB (Typical Value).Package List:1 x Digital RF Attenuator ModuleNote:1.
