Analog Voltage Variable Attenuators
Our family of voltage controlled attenuators is non-reflective, with ranges of 32 dB of 64 dB. Pin diodes are used and the frequency range is 0.25-16 GHz. They operate with a control voltage of 0 to +8 VDC and handle +27 dBm maximum input power. These attenuators are bi-directional: either SMA port may be used for an input.

Harmonic distortion is affected by input power and frequency.
Typical distortion is 50 dBc for input power less than 0.0 dBm.
Two tone intermodulation products are typically 54 dBc for input power less than 0.0 dBm.
These attenuators are bi-directional.
Either J1 or J2 can be used as input.
Other Frequency bands and Attenuation ranges available.
