The F1956 is part of a family of Glitch-FreeTM DSAs which offers very high reliability due to its monolithic silicon die construction in a compact 5 x 5 mm 32-pin TQFN package.  It has very low insertion loss is with minimal distortion and is designed with a 50Ω input and output impedance. Additionally the device is designed to have high accurate which improves SNR and/or ACLR by ensuring the system gain is achieved as close to targeted as possible.
