HMC712RF/IF射频/中频RFID的衰减器规格书PDF中文资料

General Description

the hMC712 die is an absorptive Voltage Variable Attenuator (VVA) which operates from 5 - 30 ghz and is ideal in designs where an analog DC control signal must be used to control rF signal levels over a 30 dB amplitude range. it features two shunt-type attenuators which are controlled by two analog voltages, Vctrl1 and Vctrl2. optimum linearity performance of the attenuator is achieved by first varying Vctrl1 of the 1st attenuation stage from -3V to 0V with Vctrl2 fixed at -3V. the control voltage of the 2nd attenuation stage, Vctrl2, should then be varied from -3V to 0V, with Vctrl1 fixed at 0V.
