APM1855-P29

plerowTM APM1855-P29 Low Noise & High OIP3 Medium Power Amplifier Module Features · S21 = 35.3 dB @ 1840 MHz = 34.7 dB @ 1870 MHz · NF of 1.8 dB over Frequency · Unconditionally Stable · Single 5V Supply · High OIP3 @ Low Current Description The plerowTM APM-Series is an internally matched amplifier mini-module for such application band in SMD package with the output P1dB of 29 dBm. It is compactly designed for low current consumption and high OIP3. Integrating all the components for biasing and matching within the module enhances production yield and throughput as well. It passes through the stringent DC, RF, and reliability tests. Not sample test but 100% quality control test is made before packing.

The number and size of ground via holes in a circuit board is critical for thermal RF grounding considerations. 2. We recommend that the ground via holes be placed on the bottom of all ground pins for better RF and thermal performance, as shown in the drawing at the left side.

The capacitance value may be determined by customer’s DC supply status. The capacitor should be placed as close as possible to Vs pin and be connected directly to the ground plane for the best electrical performance. DC blocking capacitors are always necessarily placed at the input and output port for allowing only the RF signal to pass and blocking the DC component in the signal. The DC blocking capacitors are included inside the APM module. Therefore, C1 & C2 capacitors may not be necessary, but can be added just in case that the customer wants. The value of C1 & C2 is determined by considering the application frequency. 2) Recommended Soldering Reflow Process Evaluation Board Layout Vs 260°C Ramp-up (3˚C/sec) 200°C 20~40 sec Ramp-down (6°C/sec) IN OUT 150°C 60~180 sec Size 40x40mm (for APM Series – 13x13mm) 4/5 www.asb.co.kr February 2008 plerowTM APM1855-P29 Low Noise & High OIP3 Medium Power Amplifier Module Channel Power vs. ACLR Test Configuration APM1855 – P29 Evaluation Board attached with Heat Sink Evaluation Board * In order to prevent damage of D.U.T (APM-Series) from heating, you must to use a properly sized heat sink for testing a module. 5/5 www.asb.co.kr February 2008
