PMI Model No. PDVAT-27G31R5G-50dB is a non-reflective, linearized, voltage controlled pin diode attenuator. This model operates over the 27.0 to 31.5 GHz frequency range and provides up to 50dB of attenuation with a control voltage range of 0 to 5 Volts (10 dB/Volt nominal). This attenuator is supplied in a small housing measuring only 1.25" x 1.25" x 0.50".
