Phase modulator circuit ?

Ata_sa16 · Nov 29, 2017

Could someone please show me some Phase modulator circuits suitable for 2.4GHz carrier frequency.

Thank you.

If the Modulation Signal is analog, applying of the derivative of that signal to a FM ( VCO..) will create PM.(VCO response time will limit the Phase Changings of the Carrier)
Or, using IQ Modulation by fixing either I or Q signal while the other is changing and using this in a IQ Modulator if the Modulation Signal is purely binary..( Only I or Q will shift on the Constellation)

Thank you I know the first one. Second could be considered.
