PMI Model No. 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 four(4) way in-phase power divider where three(3) of the outputs connect to band pass filters with center frequencies of 4.7 GHz ± 270 MHz (1 dB Bandwidth & 11 Poles), 5.1 GHz ± 400 MHz (1 dB Bandwidth and 16 Poles) and 5.5 GHz, ±270 MHz (1 dB Bandwidth & 11 Poles) respectively and the fourth port is a through port to the output. The unique PMI threshold detectors having low hysteresis characteristics and where threshold levels can be adjusted for fine tuning with low noise resistors. Unit size is 6.89" x 2.05" x 2.56" and has SMA female connectors.
