Function and Description
Power save pin for the receiver block
(IF amplifier, RSSI, 2nd down
converter). This pin is interlocked to
the internal regulator and can control
the following.

Power save pin for the transmitter
VAGC
block (quadrature modulator, up
converter, AGC circuit). This pin is
interlocked to the internal regulator
and can control the following.

–
Ground pin for the AGC and up
converter. Form as wide a ground
pattern as possible to minimize its
impedance.
–
Supply voltage pin for the up converter
block.
–
RF output pin for the up converter
block. This is an open collector
output, so an impedance matching
circuit should be attached externally.
: External attachment
Note The pin voltage is measured on Vcc=3.0 V.
