We are trying to use MMZ09332BT1 which is a 130-1000 MHz HBT RF amplifier. There are some questions about how to use the MMZ09332BT1 correctly.

  1. What is the meaning of active bias control? Does it mean that a Power Down Voltage is supplied at Pin 10 to control the bias on or off?
  2. According to the typical PA performance table at the datasheet Gain=26.3@ 3.6V, which voltage is 3.6V? Vcc,Vbias or both them?
  3. Pin 7,8,9 are all RFout, should we connect them together ? The application circuit at the datasheet only connect pin 7 and 8, will it have effect on the output power?

Thank you.
