Integrated 4 Bit Decoder
Single Positive Supply: Vdd = +5V
General Description
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.
