TD-218-RB Active

Threshold Detector

Additional Documents

Quantic PMI Model TD-218-RB is a Threshold Detector optimized for the 2 to 18 GHz frequency range. It has an internally fixed threshold level providing a minimum signal level of -30 dBm and a maximum input VSWR of 2.75:1. The threshold setting stability is constant ± 3.0 dB over the operating temperature and frequency.

Product Specifications

General Parameters:
Status: Active
Frequency Min: 2 GHz
Frequency Max: 18 GHz
Threshold: Fixed
Detected Output Type: TTL
Size: 1.5" x 1.5" x 0.5"
Frequency Range: 2 to 18 GHz
VSWR: 2.75:1 (2-18 GHz) - Measured 1.6:1
Weight: 2.0 Oz
Power Supply: +15V @ 250 mA Max - Measured 132 mA
RF 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.
Threshold Level: Internally fixed to provide a minimum signal level of -30 ± 1.5 dBm at 6 GHz
Threshold Setting Stability: ± 3.0 dB over the operating temperature and frequency range - Measured 1.3 dB
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.
Maximum RF Input: +10 dBm (without damage)
Input Operating Range: -32 to -10 dBm (2-18 GHz)
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.
