NXP AN11097: BGU7003 Low Noise Amplifier for CMMB (400 MHz to 800 MHz)
Application note for a CMMB LNA using the NXP BGU7003 SiGe MMIC, covering 400-800 MHz with circuit diagrams, PCB layout guidelines, and a complete bill of materials.
Overview
This application note provides the circuit design, PCB layout, and bill of materials for a Low Noise Amplifier (LNA) evaluation board based on the NXP BGU7003 Silicon Germanium MMIC. Targeted for Chinese Mobile Multimedia Broadcasting (CMMB) applications in the 400 MHz to 800 MHz range, the design achieves a 1.2 dB noise figure and 19.5 dB gain at 600 MHz using a 2.5 V supply. The document includes technical specifications, stability analysis, return loss plots, and component selection featuring Murata capacitors and inductors.
Use Cases
