PMI IS NOW ISO CERTIFIED!

Planar Monolithics Industries, Inc. is very proud to announce that effective December 17, 2003 PMI has become ISO 9001:2000 Certified for the following scope of registration: Research, Development, Custom Design and Manufacture of RF/ Microwave Components, Super Components and Subsystems, in the DC to 40 GHz Frequency Range.  Please click here to see PMI's ISO Certificate.


 

PMI MODEL NUMBER: TD-A-42T-818

 
PMI Model TD-A-42T-818 is a Hermetically Sealed Threshold Detector optimized for the 8 to 18 GHz Frequency Range.  It has an internally fixed Threshold Level providing a Minimum Signal Level of -42 dBm and a Maximum Input VSWR of 2.5:1.  The Threshold Setting Stability is constant +/-3.0 dB over the operating temperature and frequency.


Specifications:

  Frequency Range 8 GHz to 18 GHz
  Input Operating Range -30 dBm to -42 dBm (8-18 GHz)
  Input VSWR 2.5:1 (8-18 GHz)
  Threshold Level Internally fixed to provide a Minimum Signal Level of -42 dBm
  Threshold Setting Stability +/-3.0 dB over the Operating Temperature and Frequency Time
  Maximum Power Input +10 dBm (Without Damage)
  Detected Output The Detector 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 uS.  The maximum turn off response time measured at 10% RF to a TTL "0" shall be 100 uS.
  Connectors The Input Signal Connector shall be a SMA Female in accordance with MIL-C-39012.  The Output Signal Connection shall be a Solderable Pin (Diameter of 0.023" Minimum) with a Ground Lug next to it.  The Power Connection shall be a solderable pin (Diameter of 0.023" Minimum).
  Power Supply Voltage +12V @ 200 mA Maximum
  Size 1.50" (L) x 1.50" (W) x 0.50" (H)
  Weight 2.0 Ounces
