RF modulator manufacturers/designers
This page describes rf modulator basics and lists manufacturers of rf modulator for various technologies viz. WiMAX, WLAN, LTE, GSM, CDMA, HSPA, satellite, HF and more. It provides link to basic modulation techniques such as BPSK, QAM etc.
RF modulator is the device which modulates information to be transmitted over the medium on radio frequency (RF) carrier. To know more on 'what is modulation' refer our page in terminology section. RF modulator employs different modulation technique based on main requirement of wireless system viz. capacity and coverage. For example, it employs higher level modulation techniques such as QAM if the requirement is for more data rate i.e. capacity and BPSK if the requirement is for long distance i.e. coverage. RF modulator have been designed for various wireless technologies viz. WiMAX, WLAN, LTE, GSM, CDMA, HSPA, satellite, HF and so on. Often it is referred as IQ modulator.
