250 mW Linear Power Amplifier and T/R Switch
Designer’s Kit (AM55-0004SMB)
AM55-0004
The AM55-0004SMB Designer's Kit allows for immediate evaluation of M/A-COM's AM55-0004 integrated Power Amplifier
and T/R Switch. The evaluation board consists of an AM55-0004, recommended external surface mount circuitry, RF
connectors and a DC multipin connector, all mounted to a multi-layer FR-4 PCB. Other items included in the Designer's Kit:
a floppy disk (with typical performance data and a .DXF file of the recommended PCB layout) and any additional
Application Notes. The AM55-0004SMB PA/Switch evaluation PCB and block diagram are illustrated below with all
functional ports labeled.
