The HMC276QS24E 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
inverting the HV1 & HV2 logic control signals of one of the
HMC276QS24E 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 HMC276QS24E 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 HMC276QS24E requires DC blocking capacitors on ALL RF input and output ports.
