... Q’s of transmission lines used for impedance matching. Biasing The IAM-91563 is a voltage-biased device and is de- signed to operate in the “normal mode” from a single, +3 volt power supply with a typical current drain of only 9 mA. The internal current regulation circuit al- lows the mixer to be operated with voltages as high as +5 volts or as low as +1 ...
