General Description
Features
Functional Diagram
The HMC276LP4 & HMC276LP4E are low-cost 4x2
switch matrices in leadless QFN 4x4 mm surface
mount packages for use in RF multiplexing applicati-
ons from 200 to 3000 MHz. A positive voltage con-
trolled 4 bit decoder is integrated on the switch. The
switches 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.
