7

Vcc (Amp)

Supply voltage for RFOUT/2 output. If RFOUT/2

is not required, this pin may be left open to

conserve approximately 30 mA of current.

12

RFOUT/2

Half frequency output (AC coupled).

19

RF OUT

RF output (AC coupled).

21

Vcc (RF)

Supply Voltage, +5V

29

VTUNE

Control voltage and modulation input. Modulation

bandwidth dependent on drive source impedance. See

“Determining the FM Bandwidth of a Wideband Varac-

tor Tuned VCO” application note.

5, 11, Paddle

GND

Package bottom has an exposed metal paddle that

must be connected to RF/DC ground.
