The 6-bit digital step attenuator is programmed with a serial mode control interface. The RFDA0025 is packaged in a small 5.2mmx5.2mm leadless laminate MCM with plated through thermal vias for ultra low thermal resistance. The footprint for this module is directly compatible with most 32-pin 5mmx5mm QFNs. The amplifier’s bias choke and DC blocks are external, allowing for optimum performance over specific bands within 50MHz to 850 MHz.
