ACA2461 1218 MHz CATV CATV Push-Pull Driver Amplifier PRELIMINARY DATA SHEET - Rev 1.1 FEATURES • • • • • • • 40 to 1218 MHz Frequency Range > +45 dBmV/channel Output Power 25 dB Gain at 1218 MHz Single +24 V Supply Operating Current = 290 mA Surface Mount Package Compatible with Automatic Assembly and excellent reliability Halogen Free/RoHS Compliant APPLICATIONS • DOCSIS® and Euro DOCSIS® 3.1 (D3.1) Compliant Downstream (DS) • RF Pre-Amplifier for Node + 0 HFC and FTTC/ FTTB Networks • Final Stage Amplifier in FTTC Applications 16 Pin Wide Body SOIC with Heat Slug PRODUCT DESCRIPTION The ACA2461 is a highly linear low noise high gain RF pre-amplifier module in the industry standard SOIC-16 SMT package. Designed to drive D3.1 compliant power doublers in Deep Fiber Node CATV infrastructure applications, the module consists of two parallel amplifiers in cascade forming a push-pull optimized for low noise, low distortion, high output power per channel, and high TCP. Advanced GaAs optimizes operating current making the module an excellent choice for environmentally friendly “GREEN” applications.

Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1) Pins 2, 4, 5 and 7 should be AC-coupled. No external DC bias should be applied. (2) Pin 6 should be AC-grounded and/or pulled to ground through a resistor for current control. (3) Pins 10, 11, 14 and 15 should have no other external bias applied.
