General Description

Features

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 inte-

grated 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.

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  rst 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 ampli ers should be used at each output. The ampli er’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

The circuit board used in the  nal 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.
