I have a problem with HMC346MS8GE configuration.I need to have 30 dB linear variable attenuation,but when measure this parameter i have about 20 or 22 maximum attenuation. I connect pin v2 to voltage 0 to -3v via ad818 output and connect pin v1 to ground with other GND pins and n/c pin.  power in at port rf is about +4dBm.
