Model: CMDA-4D1G6D1G-3TTL-SFF-DP

 

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 inphase 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.
