Switch Application Circuit for 4x4 Switch Matrix
The HMC596LP4(E) switch can operate as a 4x4 switch by
connecting the 4 inputs of two switches directly together.
The VL, VH, HL, and HH inputs of the first switch should be
connected to the second switch, as illustrated.
Mirror image switch performance can be realized by invert-
ing the HV1 & HV2 logic control signals of one of the
HMC596LP4(E) switches.
The input loading impedance of two switches in parallel
should be 31.25 ohms. The output loading impedance on
each output should be 75 ohms. The interconnect RF line
between the switch’s inputs should be an RF trace with a
characteristic impedance of 62.5 ohms. This will allow the
switch to remain matched in all possible switch states.
The HMC596LP4(E) does not provide output to output (OP1
to OP2) isolation. For this reason, it is recommended that
external amplifiers should be used at each output. The
amplifier’s reverse isolation will provide output to output isolation, if this is necessary.
Each HMC596LP4(E) requires DC blocking capacitors on ALL RF input and output ports.
