The highly integrated amplifier meets the requirements of CDMA and CDMA2K 1X systems. It is a member of Celeritek’s new TrueTriangle™ family of 3V power amplifier modules. The CHP0230-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 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. 824 to 849 MHz 28.5 dBm, Cellular InGaP HBT Amplifier Module Product Specifications July 2002 (1 of 4) Functional Block Diagram Application Information The CHP0230-PM 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 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. 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. – Continued on Page 2 – TM Absolute Maximum Ratings Parameter Rating Parameter Rating Parameter Rating Collector Voltage (+Vcc) +6.0 V* Reference Voltage (Vref) +3.1 V Operating Temperature -40°C to +100°C Collector Current (Icc) 1.2 A Power Dissipation 5 W Storage Temperature -65°C to +150°C RF Input Power 7 dBm Soldering Temperature 260°C for 5 Sec.
