N/C

Not internally connected.

3RFIN

RF Input Pin, Internally matched to 50

 and DC blocked.

5VREG

First, second, and third stage bias voltage combined on the die to one external voltage. This Pin requires regu-

lated supply for best performance.

6, 7, 8

VCC

Supply voltage for the PA. Internally decoupled with approximately 100pF.

9PDETECT

Power detector voltage is proportional to RF output power. May need external decoupling capacitor for module

stability. May need external circuitry to bring output voltage to desired level.

10

RF OUT

RF output pin. This pin is matched to 50

 internally. This pin has a DC blocking cap from the collector side of

the final stage but it is an RF short at the RF OUT Pins 10 and 12 therefore an external DC blocking capacitor is

needed if DC voltage is presented to the RF OUT pins. See funtional block diagram on the first page for more

details.

16

VMODE

This pin will allow the power amplifier to switch between two modes. The first mode is the mode 1, in which this

pin needs to be logic low or floating. The second mode is mode 2 which allows the power amplifier to be in a low

current and this pin needs to be logic high.
