GaAs MMIC 4x2 SWITCH

MATRIX, 0.7 - 3.0 GHz

Features

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 is a 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.

Return Loss (Input; VL, HL, VH, HH) 700 - 3000 MHz 10 15 dB

Return Loss (Output; OP1, OP2) 700 - 3000 MHz 9 14 dB

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.
