ACA0862 - B, D 1 GHz CATV Line Amplifier MMIC PRELIMINARY DATA SHEET - Rev 1.1 FEATURES • 1 GHz Specified Performance • Flat Gain • Very Low Distortion • Excellent Input/Output Match • Low DC Power Consumption • Good RF Stability with High VSWR Load Conditions • Surface Mount Package Compatible with Automatic Assembly • Low Cost • Repeatability of Monolithic Fabrication • Meets Cenelec Standard • RoHS-Compliant Packaging S7 Package 16 Pin Wide Body SOIC with Heat Slug PRODUCT DESCRIPTION The ACA0862 family of surface mount monolithic GaAs RF Linear Amplifiers has been developed to replace, in new designs, the standard CATV Hybrid amplifiers currently in use. The ACA0862 can also replace the ACA0861 with the addition of tuning capacitors to the output (see Figure 3). The MMICs consist of two parallel amplifiers, each with 12 dB gain. The Amplifiers are optimized for exceptionally low distortion and noise figure while providing flat gain and excellent input and output return loss. The RF Input ACA0862B and ACA0862D are optimized for different output powers, and can be used separately or cascaded to support a variety of applications. A Hybrid equivalent is formed when two ACA0862 devices are cascaded between transmission line baluns. For low gain applications a single ACA0862 can be used; for higher gain applications more than two can be cascaded. See the ACA0861 application note for more information. 15dB 12dB 15dB 12dB ACA1206 ACA0862B/D Figure 1: Hybrid Application Diagram 11/2006 RF Output ACA0862 - B, D Output Stages The ACA0862B and ACA0862D are designed as output stage amplifiers. These parts can be used alone for low gain, high output level applications or can be cascaded with an ACA1206 input stage amplifier for higher gain. The ACA0862B is a low power dissipation part, while the ACA0862D is a higher power dissipation part. Cascaded, an 1 GND 2 N/C 3 RF INA 4 ACA1206 and ACA0862B provide exceptional pushpull hybrid equivalent performance; an ACA1206 and an ACA0862D cascade provides exceptional power doubling hybrid equivalent performance. An ACA0862B can also be cascaded with an ACA0862D to create a power doubler with even better distortion performance.
