MAX11014RF/IF射频/中频RFID的RFIC模块规格书PDF中文资料

General Description

The MAX11014/MAX11015 set and control bias conditions for dual MESFET power devices found in point-topoint communication and other microwave base stations. The MAX11014 integrates complete dual analog closed-loop drain-current controllers for Class A MESFET amplifier operation, while the MAX11015 targets Class AB operation. Both devices integrate SRAM lookup tables (LUTs) that can be used to store temperature and drain-current compensation data.
