Singer Instrumentation's new variable RF attenuator operates from DC to 500 MHz with an attenuator range of 10 to 60 dB. It is particularly suitable for coupling between instruments, checking transmitter output and receiver system degradation.
Power dissipation is 100 mW. Input and output impedances are 50 ohms.
Typical accuracy curves for each 10 dB of attenuation over the full frequency range provided.
