Description
Interface Schematic
25
PCS LNA
OUT
High-band LNA output (collector). Small external inductance required
for best impedance match to 50
Ω.
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.
Diode to VCC and Ground.
CMOS logic interface.
32
X2 ENABLE Logic input. High enables LO doubler; low disables LO doubler.
Diode to VCC and Ground.
CMOS logic interface.
Die
Flag
GND
Low inductance ground connection critical to proper operation.
