Attenuators
Voltage Controlled
Our family of voltage controlled attenuators is nonreflective, with attenuation ranges of 32 dB or 64 dB. Pin diodes are used and the frequency range is 0.25-16 GHz.

Control Voltage: 0 to +8 Volts typical.
Operating Power: + 20 dBm max.
Power Handling: +27 dBm max.
Operating Temperature: -25°C to + 80°C
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.
