ACA0861 - A, B, C, D 750/860 MHz CATV Line Amplifier MMIC Data Sheet - Rev 2.3 features * 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 Package Options S7 Package 16 Pin Wide Body SOIC with Heat Slug PRODUCT DESCRIPTION The ACA0861 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 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. There are four differently specified amplifiers available: two input stages and two output stages. The ACA0861A and the ACA0861C are input stages and are specified at +34 dBmV flat output. The ACA0861B RF Input and ACA0861D are output stages and are specified at +44 dBmV flat output. A Hybrid equivalent is formed when one input stage ACA0861 is cascaded with an ACA0861 output stage between two transmission line baluns. For low gain applications a single ACA0861 can be used between baluns, for higher gain applications more than two ACA0861 can be cascaded between baluns. See ACA0861 application note for more information. 12dB 12dB 12dB 12dB ACA0861A/C ACA0861B/D Figure 1: Hybrid Application Diagram 09/2008 RF Output ACA0861 - A, B, C, D Input Stages The ACA0861A and the ACA0861C are designed as input stages and are specified at +34 dBmV flat output. These parts can be used alone for low gain, low output level applications or can be cascaded with one of the ACA0861 output stages for higher gain and output signal drive level. The ACA0861A is a low power dissipation part designed to drive the ACA0861B output stage. The ACA0861C is a slightly higher power dissipation part and provides the needed distortion parameters to drive the ACA0861D output stage. 1 GND 2 N/C 3 RF INA 4 Output Stages The ACA0861B and ACA0861D are designed as output stages and are specified at +44 dBmV flat output. These parts can be used alone for low gain, high output level applications or can be cascaded with one of the ACA0861 input stages for higher gain. The ACA0861B is a low power dissipation part designed as the output stage with an ACA0861A input stage. The ACA0861D is a higher power dissipation part designed as the output stage with an ACA0861C input stage. Cascaded, an ACA0861A and ACA0861B provide exceptional push-pull hybrid equivalent performance; an ACA0861C and an ACA0861D cascaded provide exceptional power doubling hybrid equivalent performance.
