MMIC question


richard@...
 

Hi all


I am working on a USB powered device that includes an MMIC. The MMIC runs on 5 Volts (at the chip) but the spec sheet describes it as a 6-12 Volt device and gives suitable dropper resistor values. The supply is properly decoupled and fed to the device by the normal RF choke (all to the datasheet's recommendations).Is there any problem that I might encounter running an MMIC direct from the USB supply?
