5550B

SMA BIAS TEE - The Model 5550B is a very broadband coaxial bias insertion
tee and DC blocking capacitor designed to pass fast rise
pulses with minimum waveform distortion. The risetime is 20
ps with a -3 dB bandwidth extending from 100 kHz to 18 GHz.
The 5550B will safely carry 500 mA of DC current. However,
core saturation limits the low frequency response at DC
currents above 50 mA.
