GENERAL DESCRIPTION
n
PACKAGE OUTLINE
NJG1558PB1 is a dual band mixer IC with build-in local
amplifier for 800MHz and 1.5GHz dual band digital cellular phone.
One of the two Mixers of NJG1558PB1 is selected by single
control signal. The IF signal of both is output to the port.
NJG1558PB1 features low noise figure and low current
consumption.
The ultra small and thin FFP12 (Flip-Chip Fine Package) is
applied.
