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 6x6 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.

Application Information
The CHP0230-PM is a two-stage amplifier that requires a single regulated positive supply along with the unregulated battery voltage for proper operation. Vref is a regulated 2.95 reference voltage for the bias control circuitry. It can also be used as a power down mode select. Vcc is an unregulated supply voltage directly from the battery. Vcc should be applied prior to Vref and before RF input power. The CHP0230-PM 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 6. Most bypass decoupling is provided on-board. Vref is applied to pin 3. The recommended DC bypass capacitance is shown in the schematic diagram on Page 4. 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.
