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.
