Preliminary

RF2492

Pin Function Description

25

PCS LNA High-band LNA output (collector). Small external inductance required

OUT

for best impedance match to 50Ω.

26

VCC2

High-band LNA power supply connection. Small series inductance

required.

27

GND2

High-band LNA emitter. Low-inductance ground required.

28

GND2

Same as pin 27.

29

GND2

Same as pin 27.

30 PCS LNA IN High-band LNA input (base). Simple external matching required for

best performance.

31 BAND SEL Logic input. High selects high-band operation; low selects low-band

operation.

32 X2 ENABLE Logic input. High enables LO doubler; low disables LO doubler.

Die

Flag

GND

Low inductance ground connection critical to proper operation.
