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 QuadAmps™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. Vmode is a control voltage

selection between high and low gain 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.

Modulation When biased as specified, the CHP1206-QM 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 CHP1206-QM must

be soldered to the ground plane.

2. All leads of the package must be soldered to the appropriate

electrical connection.
