ply, linear power amplifier module intended for use in UMTS
handsets and wireless local loop subscriber units. The highly
integrated amplifier meets the requirements of UMTS
(WCDMA) systems. It is a member of Celeritek’s new
TrueTriangle™
family of 3V power amplifier modules.
The CHP2230-PM features additional flexibility pro-
viding independent gain and current adjustments maximizing
efficiency and performance in high and low modes of opera-

The CHP2230-PM is packaged in a low-cost, space
efficient, 6mm square, matched module that provides excellent
electrical stability and low thermal resistance. The module
operates from a fixed positive voltage and requires no external
matching which significantly reduces space, cost and enhances
ease of use.
The 6mm x 6mm package is self contained, incorpo-
rating 50 Ohm input and output matching networks optimized
for output power, linearity and efficiency.
Celeritek’s InGaP HBT technology offers a thermally
robust and reliable PAM (power amplifier module) solution.

Application Information
The CHP2230-PM is a three-stage amplifier that requires a
single regulated positive supply along with the unregulated bat-
tery voltage for proper operation. Vref is a regulated 2.95 refer-
ence voltage for the bias control circuitry. It can also be used as
a power down mode select. Vcc is an unregulated supply volt-
age directly from the battery. Vcc should be applied prior to
Vref and before RF input power. Vi adj is a control voltage
which independently adjusts the quiescent current of the device.
In addition, the gain of the amplifier can be adjusted using a
control voltage applied to the Vg adj node. It is important that

the maximum power dissipation of the package be observed at
all times and that the maximum voltage across the device is not
exceeded.
Circuit Design Considerations
Biasing
The positive Vcc supply voltages are applied to pins
3 and 4. Most bypass decoupling is provided on-board. Vref is
applied to pin 1.
The recommended DC bypass capacitance is shown in the
schematic diagram on Page 3.

Inadequate bypass capacitance and inductance around the
DC supply lines can compromise the adjacent channel power
ratio (ACPR), reduce power gain and/or create oscillations.
Modulation
When biased as specified, the CHP2230-PM will
achieve the required adjacent channel response for the digital
system specified. Celeritek tests each product under digital
modulation to ensure correlation to customer applications.
Thermal
1. The ground pad on the backside of the CHP2230-PM must
be soldered to the ground plane.
2. All leads of the package must be soldered to the appropriate
electrical connection.
