Preliminary Product Listing

Model: TD-218-RB-OPT618-N12DMB


PMI Model No. TD-218-RB-OPT618-N12DMB is a threshold detector optimized for the 6.0 to 18.0GHz frequency range.  It has an internally fixed threshold level of -12dBm ±2dBm with a low TTL output for single levels below the threshold setting.  The threshold setting stability is constant ±3.0dB over the operating temperature and frequency range.

Product Feature



Frequency Range 6.0 to 18.0GHz
Input Operating Range -20 dBm to +10 dBm
Input VSWR 2.75:1 (2-18 GHz)
Threshold Level Internally fixed to -12 ±2dBm at 12.0GHz
Threshold Setting Stability ± 3.0 dB over the operating temperature and frequency range
Maximum Input Power +10 dBm (without damage)
Detected Output The detected output signal shall be a TTL level high when the RF signal applied to the RF input exceeds the threshold level.  Any signals below the threshold level shall result in an output level of TTL low (0).  The TTL output shall be buffered in such that output loading has no effect on detector response.  The detected output shall have a drive capacity of at least two standard TTL loads.
Response Time For any RF input greater than 3 dB above threshold, the maximum turn on response time measured at 90% RF to a TTL "1" output shall be 100 nS.  The maximum turn off response time measured at 10% RF to a TTL "0" shall be 100 nS.
Connectors The input signal connector shall be an SMA female in accordance with MIL-C-39012.  The output signal connection shall be a solderable pin (ø 0.023" Minimum) with a ground lug next to it.  The power connection shall be a solderable pin (ø 0.023" Minimum).
Power Supply Voltage +15V @ 250 mA Maximum
Size 1.50" (L) x 1.50" (W) x 0.50" (H)
