Description
The CHP1206-QM is a 50 ohm matched, single sup-
ply, linear power amplifier module intended for use in Korean
handsets. The highly integrated amplifier meets the require-
ments of Korea PCS CDMA systems.It is a member of
Celeritek's new QuadAmpsTM family of 3V power amplifier
modules that are packaged in a low-cost, space efficient, 4mm
square, matched module that provides excellent electrical sta-
bility 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. A current adjustment pin (Vcntrl) is provided to improve
efficiency for the low RF power range of operation.
The 4x4 mm package is self contained, incorporating
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.

Functional Block Diagram
Application Information
The CHP1206-QM is a two-stage amplifier that requires a
single regulated positive supply along with the unregulated bat-
tery voltage for proper operation. Vref is a regulated 3.0 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. Vcntrl is a control voltage
selection between high and low power mode. The CHP1206-
QM can be operated over a range of supply voltages and bias
points by adjustment of Vref. 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
1 and 10. Most bypass decoupling is provided on-board. Vref
is applied to pin 5.
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.
