Bandpass Filters

Atlanta Micro introduces 3 passive bandpass filters implemented on chip that provide low loss and high rejection in miniature packages. These filters are useful as an IF filter in any RF system for image, LO and spur rejection. All 3 are AC coupled and matched to 50 ohms and operate over the -40°C to +100°C temperature range. AM3056 features 1 GHz center frequency, 500 MHz bandwidth and 5 mm QFN AM3055 features 2 GHz center frequency, 1 GHz bandwidth and 5 mm QFN. AM3188 features 3 GHz center frequency, 1 GHz bandwidth and 4 mm QFN.

Three-Way Splitter/Combiner

Mini-Circuits’ model ZC3PD-V24443+ is a 0° DC-pass three-way power splitter/combiner for applications from 24 to 44 GHz. The RoHS-compliant power splitter/combiner provides typical isolation of 32 dB between ports across the full frequency range. Typical full-band insertion loss (above the 4.8 dB three-way power division loss) is 1.2 dB. Full-band VSWR at all ports is typically 1.14:1 or better. The three-way power splitter/combiner maintains low phase unbalance of typically 3.1 deg across the full bandwidth with excellent amplitude unbalance of typically 0.25 dB.
