800MHz Band FRONT-END GaAs MMIC

nGENERAL DESCRIPTION

NJG1720PB1 is a front-end GaAs MMIC including a Dual

LNA, inverter, a local amplifier and a mixer, designed mainly

for 800MHz band cellular phone handsets. The LNAs

switching is made by 2 bit control signal by using inverter

circuit included in this IC.

The ultra small and thin FFP12-B1 is applied.
