Thirdly, a novel low-pass filter consisting of two improved DSCMRC connected in series is designed, simulated and measured in Section 4, which presents compact circuit size and excellent out-of -band rejection characteristics.
Finally, a novel low-pass filter incorporating two improved DSCMRCs connected in series is proposed with an excellent performance of stopband rejection from about 4 GHz up to 25 GHz.
Recently, slotted-ground-plane resonators in the low-pass filter have attracted much attention [1-20] because they have numerous advantages like circuitry size reduction and spurious response suppression.
Because the low-pass filter has unitary gain, the filter coefficients have the following property:
We plan to further expand our platform of tiny LED backlight drivers with more products that incorporate this unique digital low-pass filter to differentiate our products in the handheld market space.
A miniaturized waveguide low-pass filter with an elliptic function response for Ku-band VSAT transceiver is presented in this paper, as shown in Fig.
