The HMC276 is a low cost 4 x 2 switch matrix in leadless QFN 4 mm x 4 mm surface-mount package and a 24-lead QSOP package for use in RF multiplexing applications from 200 MHz to 3000 MHz. A positive voltage controlled 4-bit decoder is integrated on the switch. The switches may be used in either 75 Ω or 50 Ω systems. Both switch outputs (OP1 and OP2) can independently select any of the four inputs (HH, HL, VH, VL) or simultaneously select the same inputs.Note that the switch is bidirectional and the input/output functionality may be interchanged. The recommended loading impedance is 62.5 Ω on each input (HH, HL, VH, VL) and 75 Ω on each output (OP1 and OP2). All data presented were measured in a 50 Ω (input/output) system.ApplicationsCable modemCATVCellular systemsDBS
