Features
Available as Lead Free 4x2 Switch Matrix Using One IC 4x4 Switch Matrix Using Two ICs Integrated 4 Bit Decoder Single Positive Supply: Vdd = +5V
General Description
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 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 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.
