LTC1758-1/LTC1758-2 RF Power Controllers with 250kHz Control Loop Bandwidth and 40dB Dynamic Range DESCRIPTIO
The LTC®1758-2 is a dual band RF power controller for RF power amplifiers operating in the 850MHz to 2GHz range. The loop bandwidth reduction to 250kHz improves frequency stability when controlling slow turn-on PAs such as the Philips BGY280, Conexant RM009/ CX77302, Anadigics AWT6102/AWT6107 and the Hitachi PF08107/PF08123B. The LTC1758-1 is a single output RF power controller that is identical in performance to the LTC1758-2 except that one output (VPCA) is provided. The LTC1758-1 can be used to drive a single RF or dual channel module with integral multiplexer. This part is available in an 8-pin MSOP package.
