VALUE CODE:
Three or Four digits are used to express the attenuation value (available from 1 to 20 dB in 1dB increments). The letter “B” is used to
represent the decimal. Example: 10B0 = 10 dB, 1B5= 1.5 dB, etc.

The Frequency response data plotted below shows an example of VSWR
obtained in pressure contact fixtures. Data for chips which are solder attached
to matched circuit traces may exhibit even better performance.
