Marki Microwave New 14.5GHz MMIC Filter Offers Advantages Over Traditional Approaches
Introducing our first GaAs MMIC filter in QFN, the Ku-band MFB-1445SM, to complement our wide range of MMIC filters in bare die. MMIC filters are extremely small, repeatable, and reliable alternatives to traditional filter approaches and are 4x smaller than competing thin film solutions. The center frequency of the MFB-1445SM is 14.45GHz with 1dB passband of 13.6 to 15.1 GHz, excellent return loss >20dB, and >35dBc of stopband suppression. Our design approach results in no reentrant modes eliminating the need for an additional lowpass filter in ultra broadband applications. Our MFB Series filters are also extremely temperature stable – download the MFB-1445SM datasheet for plots. This filter is offered in 3x3mm QFN, with connectorized evaluation boards also available.
