ULS4X2 Datasheet






The UTC ULS4X2 is a low-cost 4 x 2 switch matrix with tone

detector in a 20-lead QFN package. It is used in RF multiplexing

applications from 200 to 3000 MHz. There is a 4 bit decoder and

tone/polarity detector integrated with RF switch which can reject

DiSEqC control signals. Switch may be used in 50/75 ohm


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.
