ABA3115 870 MHz Balanced Low Noise Linear Amplifier data sheet - Rev 2.0 features * 15 dB Gain * +5 V Nominal Supply Voltage * High Linearity * Low Noise Figure: 2.7 dB (typ.) * Characterized at +25 dBmV output power * Wide Band operation to 870 MHz * Shutdown Mode * -40 to +85 oC * RoHS-Compliant Package Applications * Driver Amplifier * CATV - Distribution / Drop Amplifiers * Set Top Boxes * Home Gateway S3 Package Modified 16 Pin SOIC PRODUCT DESCRIPTION The ABA3115 is a monolithic IC intended for use in applications requiring high linearity, such as Cellular Telephone Base Station Driver Amplifiers, CATV Fiber Receiver and Distribution Amplifiers, CATV Drop Amplifiers, CATV Set Top Boxes and Home Gateways. Offered in a modified 16 lead surface mount SOIC package that is RoHS-Compliant, it is well suited for use in amplifiers where small size, reduced component count, and high reliability are important. The ABA3115 incorporates a shutdown feature under logic control whereby power consumption is reduced to 15 mW with a +5 V supply.
