Function
Collector for FMLNA
Emitter for FMLNA
FMLNA Input
Note:
External components of PIN1, 2, 15
decide antenna impedance matching /
gain / distortion / noise figure.
Equivalent circuit

FMOUT2
GND for FMLNA
FMLNA Output1
FMLNA Output2
Note:
External components of PIN4, 6
decide output impedance matching /
gain / distortion / noise figure.
Recommended unused pin connections
is open.

AGC_ATK
GND for SUB
FMAGC Attack Point Control
Note:
External components of PIN7 decide
AGC attack point.
Cap = for DC bias cut.
Res = High -> AGC on level is low.
= Low -> AGC on level is high.
