General Description
Functional Diagram
The HMC276QS24 & HMC276QS24E are low-cost
4x2 switch matrix in a 24-lead QSOP package for
use in RF multiplexing applications from 700 to 3000
MHz. A positive voltage controlled 4 bit decoder is
integrated on the switch. The switch may be used in
either 75 ohm or 50 ohm systems.
Both switch outputs (OP1 & OP2) can independently
select any of the four inputs (HH, HL, VH, VL) or simul-
taneously select the same inputs. Note that the switch
is bi-directional and input/output functionality may be
interchanged. The recommended loading impedance
is 62.5 ohms on each input (HH, HL, VH, VL) and
75 ohms on each output (OP1 & OP2). All data pre-
sented was measured in a 50 ohm (input/output)
system.

DC Blocking And Decoupling Capacitors
The HMC276QS24(E) requires DC blocks on all 6 RF ports (OP1, OP2, VL, HL, VH, HH). Characterization on the
HMC276QS24(E) was done using 0603 size 330pF capacitors on all RF ports. A 0.01μF DC decoupling capacitor
(0603 size) is recommended for the Vdd pin.

v05.1105
GaAs MMIC 4x2 SWITCH
MATRIX, 0.7 - 3.0 GHz
Switch Application Circuit for 4x4 Switch Matrix
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.
8
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.

Evaluation PCB
8
The circuit board used in the final application should be generated with proper RF circuit design techniques.
Signal lines at the RF port should have 50 ohm impedance and the package ground leads should be connected
directly to the ground plane similar to that shown above. A generous number of ground vias should be used
to interconnect top/bottom ground planes. The evaluation circuit board shown above is available from Hittite
Microwave Corporation upon request.
