APPLICATIO S I FOR ATIO
Baseband Response
The unloaded bandwidth of the LT5537 output buffer is
10MHz. With 2.5pF loading, the output bandwidth is
approximately 6MHz. The baseband response of the LT5537
was characterized with a pulsed RF input using the setup
shown in Figure 8. The input to the LT5537 is a 200MHz
CW RF signal switched between –30dBm and –60dBm at
a rate of 600kHz. The output was connected to a FET probe
(Fluke PM8943A, 10:1 tip) which has a capacitive loading
of 2.5pF. The 10% to 90% rise and fall times are 109ns and
115ns, respectively. The input signal and output response
are shown in Figure 9.
