TABLE 2.

The summary of the limiters’ performances.

Performances		Diode limiter	Commercial limiter	BPT-based limiter
IL (dB)	20 MHz	–6.0	–6.6	–6.3
	60 MHz	–6.8	–7.7	–7.4
	100 MHz	–8.0	–8.0	–7.7
THD (dB)	20 MHz	–72.4	–74.1	–77.3
	60 MHz	–59.9	–59.9	–64.9
	100 MHz	–69.5	–66.3	–74.6
TNF (dB)	20 MHz	11	10.4	9.6
	60 MHz	10.7	10.3	8.2
	100 MHz	10.4	10.7	6.6
Bandwidth (MHz)		131	147	135
RT (ns)		89	82	43

* The IL, THD, and TNF values were measured at 50 mV_p-p. RT is the time caused by negative pulse.
