Surface Mount Tunnel Detectors
Aeroflex Control Components offers a series of tunnel detectors built in surface mount modules. These modules include complete detector circuits with DC returns and RF bypass capacitors. Options include input pads or limiters to modify the operational range or offer input protection. The small size of surface mount packages allows for easier design and lower cost. They offer high reliability and are hermetically sealed, making them ideal for operation in harsh environments. Thermal stability is one of the prime advantages of tunnel diode detectors. Frequencies range from 10MHz to 4GHz. The output will not vary more than +/-0.15dB over the temperature range of -65°C to +100°C at these low frequencies. They have high sensitivity without any bias needed for operation. Standard output polarity is negative, but positive polarity output is an option.

NOTES:
- Available in both negative and positive polarities, substitute "N" or "P" in part number.
- Diode values can be changed to alter the level of sensitivity. As sensitivity is increased, VSWR will degrade. VSWR will improve as sensitivity is lowered. Flatness and TSS will also be influenced by these changes. If your applications require something special, please contact the factory.
- VSWR measured at or below -20dBm input power level.
- Video capacitance is used for RF bypass. This value can be changed if required for video response time or other considerations. Contact the factory if value other than those shown are needed.
