This allows the coax to have a straight-line through to the load (Antenna) with very little loss. Since it is sampled via a coupler, you would need to calibrate the voltage readings which usually requires another quality lab style RF voltmeter. – K7PEH.Summary. Many RF systems incorporate an intermediate frequency (IF) that is lower than the carrier frequency and higher than the baseband frequency. An IF-based receiver is known as a heterodyne receiver. The use of an IF simplifies the design of tunable receivers and reduces the number of components that must be compatible with high frequencies.
