GENERAL DESCRIPTION
NJG1555KB2 is a mixer GaAs MMIC features low
distortion, high conversion gain and low noise figure.
NJG1555KB2 includes a mixer and a local amplifier,
and ideally suitable for 800MHz band digital mobile
phone handsets.
An ultra small & ultra thin FLP6-B2 package is adopted.

NOTE:
1) Ground terminal (2pin) should be connected with ground plane by multiple via holes
for good grounding.
Local power input terminal of local amplifier.
External matching circuit is required.
IF signal output terminal for mixer external matching circuit is required.
Please connect mixer power supply through choke inductor (L6) as shown in
test circuit.
Optional bypass capacitor terminal for mixer.
Please connect optimum capacitor if need for tuning Gc or IP3.
Local amplifier supply terminal.
Please place R1 & L4 close to this terminal as shown in test circuit.
