How is power supplied to the most common type of MMIC?
Through a capacitor and RF choke connected to the amplifier input lead
MMICs require no operating bias
Through a resistor and/or RF choke connected to the amplifier output lead✓پاسخ درست
Directly to the bias voltage (Vcc) lead
توضیح
The common three-lead MMIC has no separate supply pin, so DC is fed onto its output lead through a bias resistor and an RF choke while a series blocking capacitor keeps that DC out of the following stage. Such devices do need bias, and it is applied neither at the input nor through a dedicated supply lead.
