PIQ-85M18G-36020-CD-2

Vector Modulator

PMI Model No. PIQ-85M18G-36020-CD-2 is a Vector Modulator covering the frequency range of 85 MHz to 18 GHz. This unit provides an attenuator resolution of 0.1 dB and a phase shift resolution of 0.8º.  The attenuation is phase invariant, and the phase is amplitude invariant making it ideal for nulling unwanted signals. The unit can be specifically calibrated for any number of 100 MHz bands within the full operating frequency range of 85 MHz to 18 GHz.
