Quantic PMI Model CMDA-4D1G6D1G-3TTL-SFF-DP is a 4.1 to 6.1 GHz Coarse Microwave Discriminator centered at 5.1 GHz. Using state of the art MMIC and MIC technology, the coarse microwave discriminator assembly consists of a 4-way in phase power divider where three of the outputs connect to band pass filters with center frequencies of 4.7 ± 0.27 GHz (1 dB BW & 11 Poles), 5.1 ± 0.4 GHz (1 dB BW and 16 Poles) and 5.5 ± 0.27 GHz (1 dB BW & 11 Poles) respectively and the fourth port is a through port to the output. The unique PMI threshold detectors have low hysteresis characteristics and where threshold levels can be adjusted for fine tuning with low noise resistors. Package size is 6.89" x 2.05" x 2.56" with SMA female connectors.
