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:

|
Input VSWR |
2.5:1 (8-18 GHz) |
|
Threshold Level |
Internally fixed to provide a
Minimum Signal Level of -42 dBm |
|
Threshold Setting Stability |

|
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). |
