Frequently Asked Questions
What coupling values are available for KRYTAR couplers up to 26.5 GHz?
The listed product groups offer nominal coupling values of 6, 10, 13, 16, 20 and 30 dB. The available value depends on the required lower frequency limit.
Which KRYTAR directional coupler covers 1–26.5 GHz?
KRYTAR 2606, 2610, 2620 and 2630 cover 1.0–26.5 GHz with nominal coupling values of 6, 10, 20 and 30 dB respectively.
What is the difference between a 10 dB and 20 dB directional coupler?
An ideal 10 dB coupler delivers approximately 10% of the main-line power to the coupled port. An ideal 20 dB coupler delivers approximately 1%. The 20 dB coupler therefore causes less power to be sampled but produces a lower coupled-port signal.
Can these couplers measure reflected power?
A directional coupler can be oriented to sample forward or reflected power. Measurement accuracy depends on directivity, impedance match, calibration and the performance of the connected measurement instrument.
Are S-parameter files available?
S-parameter data may be available from the manufacturer or supplier. Request the data for the exact model and verify that it covers the required frequency range before using it in simulation or calibration.
