F1912数据手册开发板套件编程器的射频评估开发套件开发板规格书PDF

描述 Description

The F1912 is part of a family of Glitch-FreeTM DSAs which offers very high reliability due to its monolithic silicon die construction in a compact 4mm x 4mm 20-pin package QFN package.  The silicon design has very low insertion loss and low distortion (> +60 dBm IP3I.)  The device has pinpoint accuracy and settles to final attenuation value within 400 nsec.  Most importantly, the F1912 includes IDT’s Glitch-FreeTM technology which results in low overshoot & ringing during MSB transitions
