NJG1505R
SPDT SWITCH GaAs MMIC
n
GENERAL DESCRIPTION
NJG1505R is a GaAs SPDT switch MMIC which features
high isolation and low loss and ideally suitable for switching
transmit/receiving signal of synthesizer.
This switch is operated in the wide frequency range from
1MHz to 3GHz at low voltage operation from 2.5V with very
small VSP8 package.
