ADL5205ACPZ-R7

ADL5205 is a digitally controlled, wide bandwidth, variable gain dual amplifier (DGA) that provides precise gain control, high output third-order intercept (OIP3) and a near constant noise figure for the first 12dB of attenuation. The excellent OIP3 performance of 48.5dBm(at 200MHz, 5V, high performance mode, and maximum gain) makes the ADL5205 an excellent gain control device for a variety of receiver applications. For wide input dynamic range applications, the ADL5205 provides a broad 35dB gain range with a 1dB step size. Typical application includes differential analogue-to-digital converter(ADC) drivers, high intermediate frequency (IF) sampling receivers, high output power IF amplification and instrumentation.
