Features
4x2 SWITCH MATRIX USING ONE IC
4x4 SWITCH MATRIX USING TWO IC's
INTEGRATED 4 BIT DECODER
SINGLE POSITIVE SUPPLY: Vdd = +5V
SUITABLE FOR DBS SWITCHING APPLICATIONS
V03.0101
General Description
The HMC276QS24 is a 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 DBS, CATV,
cable modem, or cellular systems.
Both switch outputs (OP1 & OP2) can indepenÂdently 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) sysÂtem.
Guaranteed Performance, For Vdd = +5V in a 50 Ohm system, -40 to +85 deg C
