Pole/Zero’s newnew integrated microwave filter (IMF) series of digitally tunable bandpass and notch filters features accelerated tuning speeds packed in very small, lightweight QFN packages. IMF frequency hopping filters are available in multiple frequency bands across the 4 to 24 GHz frequency range, with tune times <100 ns via GPIO tuning control (0 V OFF, +5 V ON) of 16 discrete tunable steps.

Performance capabilities include: phase noise: -145 dBc/Hz at 10 kHz offset; Pin: +30 dBm (10 percent BW); IIP3: +35 dBm min. +40 dBm typ.; insertion loss: 3.4 dB avg. for 10 percent BW; selectivity: 20 dBc at fc ± 10 percent (4 percent BW); +5 V at 20 μA typical DC power.

Package sizes are as small as 4.1 x 4.1 x 1.5 mm QFN packages for >10 GHz bandpass filters and 7 x 7 x 2 mm QFN packages for >10 GHz notch filters, and <10 GHz bandpass Filters; all operating over -40C to +85C.

The reduced size, weight, power consumption and cost (SWaP-C) of Pole/Zero’s IMFs make them suitable for applications on radar, electronic warfare, SATCOM-On-The-Move (SOTM), RF front end and commercial platforms.
