Pin

Function

Description

Interface Schematic

1NC

Not connected. May be connected to ground (GND).

2RF IN

RF input. See evaluation board schematic for details.

3RF IN

RF input. See evaluation board schematic for details.

4NC

Not connected. Note: Connection of VC1 at this pin will not damage the

RF5152 or adversely affect RF5152 performance.

5VCC

Supply voltage for the bias reference and control circuits. May be con-

6VB1/VB2

Bias current control voltage for the first and second stages.

7VB3

Bias current control voltage for the third stage.

8NC

Not connected.

9PDETECT

Provides an output voltage proportional to the output RF level.

10

RF OUT

RF output. The output requires external matching components which con-

sist of a one or two shunt capacitors and a series capacitor for DC blocking.

11

RF OUT

Same as pin 10.

See pin 10.

12

RF OUT/

VC3

RF output and bias for the output stage. The power supply for the output

transistor needs to be supplied to this pin. This can be done through a

quarter-wave (

o/4) length microstrip line that is RF grounded at the other

end, or through an RF inductor that supports the required DC current. See

evaluation board schematic.

See pin 10.

13

NC

Not connected. May be connected to ground (GND).

14

VC2

Second stage power supply input. Connect as shown on evaluation board

schematic.

15

NC

Not connected. May be connected to ground (GND).

16

VC1

First stage power supply input. Connect as shown on evaluation board

schematic.

Pkg

Base

GND

Ground connection. The back side of the package should be connected to

the ground plane through as short a connection as possible (e.g., PCB vias

under the device are required).
