描述 Description

The A7539 is a high isolation 4 x 2 switch matrix in a 24-lead QFN 4x4 package for RF multiplexing applications from 200 to 3000 MHz. The switch is enabled 16 states by 4 inputs controlled 4 bit decoder in 50/75 ohm systems.

A7539’s outputs (OP1 & OP2) can be independently selected by 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.

应用 Application

4*2 Switch Matrix for 0.2 -3.0 GHz Applications:
 LNB
