Phase modulator ke potoloho eo ho eona karolo ea leqhubu la sepalangoang e laoloang ke lets'oao le feto-fetohang. Ho na le mefuta e 'meli ea ho feto-fetoha ha leqhubu la sine: ho feto-fetoha ha karolo e tobileng le ho feto-fetoha ha mekhahlelo e sa tobang. Molao-motheo oa ho feto-fetoha ha mokhahlelo o tobileng ke ho sebelisa lets'oao la modulating ho fetola ka ho toba liparamente tsa loop ea resonant, e le hore lets'oao la sephethephethe ka leqhubu la resonant le hlahise phetoho ea mohato le ho theha leqhubu la ho feto-fetoha ha mohato; Mokhoa o sa tobang oa mokhoa oa ho feto-fetoha ha maemo o qala ho fetola boholo ba leqhubu le fetotsoeng, ebe o fetola phetoho ea amplitude ho phetoho ea mohato, e le ho fihlela modulation oa mohato. Mokhoa ona o entsoe ke Armstrong ka 1933, o bitsoang Armstrong modulation method

Sesebelisoa sa microwave phase shifter se laoloang ka mokhoa oa elektroniki ke marang-rang a li-port tse peli a sebelisetsoang ho fana ka phapang ea mohato pakeng tsa tlhahiso le matšoao a kenyang a ka laoloang ke lets'oao la taolo (ka kakaretso ke DC bias voltage). Palo ea phetoho ea mohato e ka fapana khafetsa ka lets'oao la taolo kapa ka boleng bo reriloeng esale pele. Li bitsoa analog phase shifters le digital phase shifters ka ho latellana. Phase modulator ke "binary phase shift keying modulator" ho sistimi ea puisano ea microwave, e sebelisang leqhubu le tsoelang pele la lisekoere ho fetola lets'oao la mojari. Sine wave phase modulation e ka aroloa ka ho toba mohato oa ho feto-fetoha le ho feto-fetoha ha mekhahlelo e sa tobang. Ka ho sebelisa kamano ea hore sine wave amplitude Angle ke karolo ea maqhubu a hang-hang, maqhubu a feto-fetohang a ka fetoloa ho ba leqhubu la modulated (kapa ka tsela e fapaneng). Potoloho ea modulator e sebelisoang haholo ka ho toba ke varactor diode phase modulator. Potoloho ea modulation ea mekhahlelo e sa tobang e rarahane ho feta potoloho ea modulation ea mohato o tobileng. Molao-motheo oa eona ke hore tsela e le 'ngoe ea lets'oao la sephethephethe e fetoloa ke 90 ° phase shifter mme e kena ka amplitude-modulator e leka-lekaneng ho hatella amplitude modulation ea mojari. Ka mor'a ho fokotsa ka mokhoa o nepahetseng, letšoao le fumanoeng le eketsoa tseleng e 'ngoe ea sephethephethe ho hlahisa pontšo ea amplitude-modulating. Potoloho ena e khetholloa ke botsitso bo phahameng ba maqhubu, empa phetoho ea mekhahlelo e ke ke ea e-ba khōlō haholo (ka kakaretso e ka tlase ho 15 °) kapa ho sotha ho tebileng. Modulator ea mekhahlelo e bonolo e sebelisoa hangata ho li-transmitters tsa FM.
