Pin Function Description

Interface Schematic

1

RF IN

RF input pin. This pin is not internally DC blocked and requires an

external blocking capacitor.

2

GND1

Ground connection for the LNA. Keep traces physically short and con-

nect immediately to ground plane for best performance.

3

GND2

Ground connection for the bias circuits.

4

IPSET

This pin selects the internal current setting when CMOS level “low”, and

the external current setting when this pin is CMOS level “high”.

5

ENABLE Power down control. This is a CMOS input. When this pin is CMOS

“high” the device is enabled. When the level is CMOS “low” the device

is shut off and a controlled attenuator is turned on.

6

VCC

Power supply for the bias circuits.

7

ISET

This pin sets the current for the device.

4

8

RF OUT RF output pin. Bias for the LNA is provided through this pin, hence it

should be connected to VCC through an inductor.
