Gates connected to these RF pads must have a grounded silicide-block (SBLK) NMOS protection with a charged device model (CDM) resistor. Output drivers connected to these RF pads must have resistor ...

That precision is fine for low-frequencycircuits, but RF circuits usually need50Ω traces for proper circuit operation.Parts get smaller, but the laws of physicsdon’t change. Thus, a microstrip traceon ...

What kinds of circuits can be 3D printed? Not everything can be manufactured using this approach, however. “The industry today can print a 2D circuit, and we can sort of print a 3D circuit, meaning ...

These can range from TV tuner types of cans, simple plastic moldings that have been coated with conductive material, or expensive machined chunks of aluminum, purpose made just for our circuit board.

Digital circuits are switching circuits operating at much higher voltage levels, around one volt. The switching noise from these digital circuits can overwhelm or saturate the sensitive RF receiver, ...

Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the basics.

The last chapter will provide a trip down memory lane for some readers—a sampling of circuits of particular interest in RF history, including the Regency TR-1 transistor radio design and the ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks.
