RFDA2025

500 - 2500 MHz Serial Controlled Digital Variable Gain Amplifier, 6-Bit, 0.5 dB Steps

Qorvo's RFDA2025 is a digital controlled variable gain amplifier featuring high linearity over the entire gain control range. The 6-bit digital step attenuator is programmed with a serial mode control interface. The RFDA2025 is packaged in a small 5.2mm x 5.2mm 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 5mm x 5mm QFNs. The output amplifier is externally matched, allowing for optimum performance over specific bands within 500MHz to 2500MHz.
