What role does the mixer play in the design of RF receivers?
The mixer is a key stage of the RF signal chain in the superheterodyne (super) receiver architecture. It allows the receiver to be tuned over a wide frequency band of interest and then convert any desired received signal frequency to a known fixed fr

Why use automatic mixing technology?
Automatic mixing technology is not a new technology. Since the 1970s, various types of automatic mixers and various patents have been transformed into a function in DSP equipment. The form of the automatic mixer is gradually changing from an independ

Constraints of silicon tuner design
Televisions, video recorders, set-top boxes and broadband cable receivers all have a common element: the tuner. Although all other electronic components in these devices shrink as semiconductor technology shrinks, consumer applications often use huge
