N/C

No Connection. These pins may be connected to RF/

DC ground. Performance will not be affected.

RFOUT/4

Divide-by-4 output. DC block required.

6Vcc (Dig)

Supply voltage for prescaler. If prescaler is not

required, this pin may be left open to conserve

approximately 100 mA of current.

VTUNE

Control voltage and modulation input. Modulation

bandwidth dependent on drive source impedance.

Paddle

GND

Package bottom has an exposed metal paddle that

must be connected to RF/DC ground.
