Ordering Information

SL1914 Preliminary Information Figure 2 Pin Connections MP8 SPOT REF. Vcca RFIP Vee AGC Vccb N/C OP OPB Quick Reference Data Characteristic Units Operating frequency 950 - 2150 MHz Input DSB NF at max gain 8 dB Maximum conversion gain 20 dB Minimum conversion gain -10 dB IPIP3 2T 117 dB µV IPIP22T 127 dB µV Functional Description The SL1914 is a bipolar, low noise AGC amplifier designed primarily for application in satellite tuner front ends. It contains a low noise input amplifier, an AGC stage with a minimum of 30dB of gain control and a 75 Ohm output drive. It replaces all active circuitry in conventional architectures. The typical key performance numbers under nominal load ambient and supply conditions are contained in table headed Quick Reference Data.
