  • Patent number: 7945221
    Abstract: A transmitter device for wireless communication equipment, comprises at least one path (P1) comprising i) a low-pass filter (LPF 1+, LPF1?) for filtering differential signals and applying a chosen first attenuation to each of them to decrease their amplitudes, ii) a differential transconductor (TC1+, TC1?) arranged for applying a chosen second attenuation to each differential signal coming from the low-pass filter (LPF1+, LPF1?) to decrease its continuous component, and iii) a mixer (M1) for mixing separately the differential signals delivered by the transconductor with local oscillator carriers at a chosen radio frequency to deliver output RF signals to be transmitted. The transconductor (TC1+, TC1?) comprises two original cells (OC) for defining two original signals from the differential signals having the first attenuation, and N first and N second signal copy cells (CC1-CC6) each arranged for generating a copy of one of the original signals.

  • Publication number: 20100022196
    Abstract: A transmitter device for wireless communication equipment, comprises at least one path (Pl) comprising i) a low-pass filter (LPF 1+, LPFl?) for filtering differential signals and applying a chosen first attenuation to each of them to decrease their amplitudes, ii) a differential transconductor (TC1+, TCl?) arranged for applying a chosen second attenuation to each differential signal coming from the low-pass filter (LPF1+, LPFl?) to decrease its continuous component, and iii) a mixer (Ml) for mixing separately the differential signals delivered by the transconductor with local oscillator carriers at a chosen radio frequency to deliver output RF signals to be transmitted. The transconductor (TC1+, TCl?) comprises two original cells (OC) for defining two original signals from the differential signals having the first attenuation, and N first and N second signal copy cells (CC1-CC6) each arranged for generating a copy of one of the original signals.
