4x4 Switch Matrix Using Two ICs
Integrated 4 Bit Decoder
• Cable Modem
• CATV
• Cellular Systems
• DBS
Single Positive Supply: Vdd = +5V
General Description
Functional Diagram
The HMC276QS24 is a low-cost 4x2 switch matrix
in a 24-lead QSOP package for use in RF multiplex-
ing 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
simultaneously select the same inputs. Note that
the switch is bi-directional and input/output function-
ality may be interchanged. The recommended load-
ing impedance is 62.5 ohms on each input (HH,
HL, VH, VL) and 75 ohms on each output (OP1
& OP2). All data presented was measured in a 50
ohm (input/output) system.

DC Blocking And Decoupling Capacitors
The HMC276QS24 requires DC blocks on all 6 RF ports (OP1, OP2, VL, HL, VH, HH). Characterization on the
HMC276QS24 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.

MICROWAVE CORPORATION
GaAs MMIC 4x2 SWITCH
MATRIX, 0.7 - 3.0 GHz
Switch Application Circuit for 4x4 Switch Matrix
The HMC276QS24 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 illus-
trated.
Mirror image switch performance can be realized by
inverting the HV1 & HV2 logic control signals of one
of the HMC276QS24 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 imped-
ance of 62.5 ohms. This will allow the switch to
remain matched in all possible switch states.
14
The HMC276QS24 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 HMC276QS24 requires DC blocking capacitors on ALL RF input and output ports.

Evaluation PCB

J1
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 Micro-
wave Corporation upon request.
