General Description
Functional Diagram
The HMC276LP4 & HMC276LP4E are low-cost 4x2
switch matrices in leadless QFN 4x4 mm surface
mount packages for use in RF multiplexing applicati-
ons from 200 to 3000 MHz. A positive voltage con-
trolled 4 bit decoder is integrated on the switch. The
switches 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 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 presented was measured in a 50 ohm (input/
output) system.

DC Blocking And Decoupling Capacitors
The HMC276LP4 requires DC blocks on all 6 RF ports (OP1, OP2, VL, HL, VH, HH). Characterization on the
HMC276LP4 was done using 0402 size 330pF capacitors on all RF ports. A 1,000 pF DC decoupling capacitor (0603
size) is recommended for the Vdd pin.

GaAs MMIC 4x2 SWITCH
MATRIX, 0.2 - 3.0 GHz
Switch Application Circuit for 4x4 Switch Matrix
The HMC276LP4 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
HMC276LP4 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 HMC276LP4 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 HMC276LP4 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 and exposed paddle
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.
