Description
Interface Schematic
Not connected. May be connected to ground (GND).
RF input. See evaluation board schematic for details.
RF input. See evaluation board schematic for details.
Not connected. Note: Connection of VC1 at this pin will not damage the
RF5152 or adversely affect RF5152 performance.
Supply voltage for the bias reference and control circuits. May be con-
nected with VC1, VC2 and VC3 with a single-supply voltage as long as V_CC
does not exceed 3.3V_DC in this configuration.
Bias current control voltage for the first and second stages.
Bias current control voltage for the third stage.
Not connected.
Provides an output voltage proportional to the output RF level.
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.
RF OUT
BIAS
Same as pin 10.
See pin 10.
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.
Not connected. May be connected to ground (GND).
See pin 10.
Second stage power supply input. Connect as shown on evaluation board
schematic.
Not connected. May be connected to ground (GND).
First stage power supply input. Connect as shown on evaluation board
schematic.
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).
