This DBTC series of directional couplers operates in a frequency range from 5 to 2000 MHz and features nine different coupling values that range from 9 to 20 dB. These couplers deliver flat coupling over broad multi-octave bandwidths.
The 50 and 75 Ω models stand 0.15" square and employ LTCC construction to embed circuits inside the ceramic base thus realizing good temperature stability, repeatability and ruggedness. Patented with additional patent pending.
Price: from $1.99 each (25).
