AJMRTC PE4302 digital RF step attenuator module is built around the PE4302 UltraCMOS RF attenuator chip. It achieves fine 0.5 dB resolution across full 031.5 dB attenuation range over DC4 GHz bandwidth while maintaining outstanding signal linearity.
Designed with standard 50ohm radiofrequency impedance, SMAfemale connectors are fitted for RFIN and RFOUT. Both serial and parallel control modes are supported, allowing microcontrollerbased automatic adjustment. Users can set default attenuation value on powerup to fit project requirements. Low insertion loss helps preserve signal integrity during attenuation operation.
It is commonly used in RF laboratory measurement, wireless device debugging, signal simulation and prototype development. Signal source, host controller and test instruments are not included. Do not feed input power higher than +24 dBm to prevent chip burnout.
