Maxim recommends using microstrip and stripline tech-
niques to obtain full bandwidth. To ensure that the PC
board does not degrade the amplifier’s performance,
design it for a frequency greater than 1GHz. Pay care-
ful attention to inputs and outputs to avoid large para-
sitic capacitance. Whether or not you use a constant-
impedance board, observe the following guidelines
when designing the board:
• Don’t use wire-wrap boards because they are too
• Don’t use IC sockets because they increase parasitic
• Use surface-mount instead of through-hole compo-
• Use a PC board with at least two layers; it should be
• Keep signal lines as short and as straight as possi-

mode rejection. Beyond this range, the amplifier output
is a nonlinear function of the input, but does not under-
go phase reversal or latchup.

When the MAX4213/MAX4218 are disabled, the amplifi-

and the low 2pF output capacitance make these parts
ideal in RF/video multiplexer or switch applications. For
larger arrays, pay careful attention to capacitive load-
ing. See the Output Capacitive Loading and Stability
section for more information.
