In older designs such as the tuned radio frequency receiver (TRF), all of the receiver stages had to be simultaneously tuned.

In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception. The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process called heterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequenci… WebJun 25, 2024 · Some fixed wireless and mobile providers have licensed frequencies that fit between 7 GHz and 60 GHz.
